Answer: D - (x,y) (x+9, y + 2)
Explanation:
Logically, the coordinates on point A say (-5, 1). Looking at answer D, +9 added with -5 from coordinate A on Segment AB is 4 on Segment A'B'. The same goes with the y-coordinate on segment AB. 1 + 2 = 3 on segment A'B'.
Since point B on segment AB & A'B' is unknown, we don't need to know anything about it.
Hence, the answer is D.
