Answer: x=-10, y=-5 or -2/1. And it's dilated by 2. & i believe the scale factor is 2.
Explanation:
What i did was simply count from the radius (the tiny dot in the center) up, and i counted 3, and did the same w/ the A' so I got 6, why makes me assume the scale factor is 2. then i did rise/run and i went 10 left and 5 down. So that makes -10,-5.
