Answer:
B. (-1,13)
Explanation:
Given translation
(x,y)→(x-2,y-6)
moves point 2 units to the left and and 6 units down.
If a point after this translation has coordinates (-3,7), then its preimage has coordinates (-1,13) (translate the image point 2 units to the right and 6 units up to get preimage point).
