Do You See What I See?

Activity Overview

In this activity, students will discover how pictures formed by graphing ordered pairs can be stretched (and shrunk) by multiplying (and dividing) the coordinates.

Key Steps

  • Image

    Students will discover how pictures formed by graphing ordered pairs can be stretched (and shrunk) by multiplying (and dividing) the coordinates.

    First, students will identify the coordinates of each point of the given image, enter the x- and y-values into L1 and L2, and graph.

  • Image

    Then, students will double the x-values in each ordered pair and observe the change in the graph. Next they will manipulate the y-values and observe the changes.

  • Image

    Finally, students will make predictions about the impact different multipliers will have on the image.
