1. Read this first

   Use this

   Coordinate grid, all four quadrants, each square one unit, 20 squares across (−10 to 10), origin in the middle. The kite drawing with corner D(2, 5) marked and an arrow 6 units left from D; the image is not drawn. Table old | new: the x row 2 | 2 − 6.

2. 1.

   Ari slides a kite drawing 6 units left on a grid. Corner D is at (2, 5). In the table, the x row is 2 → 2 − 6. What is the x-coordinate of D′?

   -4

3. Use this
