4 - Reflect over y=-x

Directions: 1. Use the app below to plot 6 different points.  To plot a point chose the point tool. Plot a point in each quadrant and then one of each axis. 2. Next, use the input box to graph the line y=x 3. Use the reflect tool to reflect each of your 6 points across the y=-x.   3. On some scratch paper, write the coordinates of each pre-image and its image.  Compare each pre-image to its image and identify a common rule that would move the points in the same way.  4. Write your rule in the space below.

Compare the coordinates for your pre-image points with their respective image coordinates. Write a rule that could be used to move the points in the same way.
