Plot points on a graph

Plot points on a graph

Here you will learn about plotting points on a graph, including how to identify the quadrant or axis the points are on. You will also learn how to find the distance between points on the coordinate plane.

Students first learn how to plot points in the 6th grade with their work in the number system and expand that knowledge through middle school and high school when graphing linear equations.

What is plot points on a graph?

To plot points on a graph means to graph points on the coordinate plane where the point, also called an ordered pair, is in the form of katex is not defined

When plotting a point on a graph, always start from the center, which is called the origin and has coordinates katex is not defined

Then move horizontally the amount of units represented by the katex is not defined-coordinate, and move vertically the amount of units represented by the katex is not defined-coordinate. The katex is not defined-coordinate and the katex is not defined-coordinate are represented by rational numbers.

For example, let’s plot the points katex is not defined and katex is not defined on the coordinate plane.

katex is not defined represents the katex is not defined-coordinate and katex is not defined represents the katex is not defined-coordinate.

This means you do not move left or right on the katex is not defined-axis, you just move up katex is not defined places on the katex is not defined-axis. This point is on the katex is not defined-axis.

katex is not defined represents the katex is not defined-coordinate and katex is not defined represents the katex is not defined-coordinate.

This means that you move four units right on the katex is not defined-axis and katex is not defined units up on the katex is not defined-axis. This point is on the katex is not defined-axis.

On this graph, each unit or tick mark represents katex is not defined unit.

For example, the table represents coordinates. Let’s plot them on the coordinate plane.

Notice how each of the points lands in one of the four quadrants on the coordinate plane. Each unit on this coordinate plane represents katex is not defined unit.

  • katex is not defined is in Quadrant I because both the katex is not defined and katex is not defined coordinates are positive.
  • katex is not defined is in Quadrant II because the katex is not defined-coordinate is negative and the katex is not defined-coordinate is positive.
  • katex is not defined is in Quadrant III because both the katex is not defined and katex is not defined coordinates are negative.
  • katex is not defined is in Quadrant IV because the katex is not defined-coordinate is positive and the katex is not defined-coordinate is negative.

Distance between points on a graph

We can find the distance between two points on a graph by counting the number of units between the points.

For example,

Plot the point katex is not defined and the point katex is not defined Find the distance between the points.

Plot Points on a Graph image 5

To find the distance from point katex is not defined to point katex is not defined, count the number of units. The distance from point katex is not defined to point katex is not defined is katex is not defined units.

For example,

Let’s plot the polygon on the coordinate plane with vertices at katex is not defined katex is not defined, and katex is not defined.

Plot Points on a Graph image 6

Let’s find the side lengths of the plotted rectangle. To do this, count the number of units from one point to the next.

The distance from point katex is not defined to point katex is not defined is katex is not defined units.

The distance from point katex is not defined to point katex is not defined is katex is not defined units.

The distance from point katex is not defined to point katex is not defined is katex is not defined units.

The distance from point katex is not defined to point katex is not defined is katex is not defined units.

The distance between points is always positive because distance is a positive measurement.

Now that you know the side lengths, you can find the perimeter of the rectangle katex is not defined

To find the perimeter of a rectangle, add up each of the side lengths or use the formula, katex is not defined

The perimeter of rectangle katex is not defined is katex is not defined units OR katex is not defined units

Common Core State Standards

How does this relate to 6th grade math?

  • Grade 6 – Number System (6.NS.C.6.b)
    Understand signs of numbers in ordered pairs as indicating locations in quadrants of the coordinate plane; recognize that when two ordered pairs differ only by signs, the locations of the points are related by reflections across one or both axes.

  • Grade 6 – Expressions and Equations (6.EE.C.9)
    Use variables to represent two quantities in a real-world problem that change in relationship to one another; write an equation to express one quantity, thought of as the dependent variable, in terms of the other quantity, thought of as the independent variable. Analyze the relationship between the dependent and independent variables using graphs and tables, and relate these to the equation.

  • Grade 6 – Geometry (6.G.A.3)
    Draw polygons in the coordinate plane given coordinates for the vertices; use coordinates to find the length of a side joining points with the same first coordinate or the same second coordinate. Apply these techniques in the context of solving real-world and mathematical problems.

How to plot points on a graph

In order to plot points on a graph:

  1. Identify the horizontal (katex is not defined-value) and vertical position (katex is not defined-value) of the ordered pair.
  2. Follow the gridlines until the two values meet and draw a point.
  3. Identify which axis or quadrant the point(s) is in.

In order to find the distance between points on a graph:

  1. Identify the horizontal (katex is not defined-value) and vertical position (katex is not defined-value) of the ordered pair.
  2. Follow the gridlines until the two values meet and draw a point.
  3. Connect the points.
  4. Count the units between the points.

Teaching tips for plot points on the coordinate plane

  • Worksheets play an important role when students are learning to plot on a coordinate plane, but they are not the only option. There are digital coordinate planes available where students can easily change the scale and explore grids with very small or very large scales that would be harder to represent on paper. You can also utilize a tiled floor or wall to create a physical version of the coordinate plane within the classroom.

  • Coordinate planes have many practical uses in the real world as well as in the art world. Incorporating projects where students can be creative with plotting points on the coordinate plane helps them to see their usefulness.

  • Expose students to digital resources which can enhance the learning experience, such as using the free Desmos graphing calculator to plot points and find the distance between the points instead of doing it by hand with graph paper.

Easy mistakes to make

  • Mixing up the values of an ordered pair
    For example, plotting the point katex is not defined as the point katex is not defined

  • Numbering or counting the spaces between the gridlines incorrectly
    For example, not using a consistent way of counting the gridlines. Each space should represent an equal amount. Starting from the origin, count with consistency to the right and left. If you count katex is not defined unit to the right, then you must count katex is not defined unit left.

  • Forgetting to use parentheses and a comma
    The parentheses and the comma are necessary when writing a coordinate. Coordinates can be incorrectly written as katex is not defined without the parentheses, this is just a list of numbers; katex is not defined is a coordinate.

Plot points on a graph FAQs

What is the cartesian plane?

This is the same as a coordinate plane. This name refers to the French mathematician Rene Descartes who is credited with incorporating the use of the coordinate plane into mathematics.

What are coordinate planes used for?

Coordinate planes have many uses in the real world and come up extensively in upper level math topics like coordinate geometry, algebra, trigonometry, and statistics.

Can coordinates be decimals or fractions?

Yes, an ordered pair can be any rational number.

What are linear equations and quadratic equations?

Linear equations are equations that form straight lines on the coordinate plane, and quadratic equations form curves called parabolas on the coordinate plane. You will begin to graph linear equations in the 7th grade.
