Answer:
option D
Explanation:
(-9, 1) and (3, 1) these points are 12 units apart
- looking at change in x value
- 9 to 0 is 9
- 3 to 0 is 3
- visual representation below
(6, 2) and (6, 10) these points are 8 units apart
- looking at change in y value
2 + x = 10
-2 + 2 + x = 10 - 2
x = 8
- visual representation below
(-7, 8) and (-3, 8) these points are 4 units apart
- looking at change in x value
-7 + x = -3
+7 - 7 + x = -3 + 7
x = 4
- visual representation below
(2, 2) and (8, 2) these points are 6 units apart
- looking at change in x value
2 + x = 8
- 2 + 2 + x = 8 - 2
x = 6
