The pre-image is the reverse of the image, so we need to alter the rule used.
The given rule to find the image is (x minus 6, y + 8). We need to add to x and subtract from y, so the rule becomes (x + 6, y minus 8).
Add 6 to the x coordinate, and subtract 8 from the y coordinate.
-4 + 6 = 2
1 – 8 = -7
The new coordinates, or the pre-image, is (2, -7).
Answer:
B. (2, -7)
I hope this helps :)
