Square ABCD was translated using the rule (x, y) - (x-4, y + 15) to form A'B'C'D'. What are the coordinates of point Din
the pre-image if the coordinates of point D' in the image are (9,-8)?
(13,-23)
O (5,7)
O (181)
O (-6,-4)

  (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
