Rule A: (x, y) -> (-x, y) Step 3 Directions for Graphing IMAGE triangle on coordinate plane

Use the graph above to plot the image's coordinates. a. Use the INPUT line, located below the graph. to type in the IMAGE's coordinates for A. b. a point D should appear c. repeat for the B & C coordinates d. you should have three points (if the points are connected,) that look congruent to the pre-image triangle ABC. If it doesn't look congruent, check your points from Step 2.
