Answer:
(13,-23)
Step-by-step explanation:
Comparing the image coordinates to the transformation rule, you see that ...
(x -4, y +15) = (9, -8)
Adding (4, -15) to these coordinates, we get ...
(x -4, y +15) +(4, -15) = (9, -8) +(4, -15)
(x-4+4, y+15-15) = (9+4, -8-15)
(x, y) = (13, -23) . . . . coordinates of D
