Answer:

Explanation:
The transformations are ...
(x, y) ⇒ (-y, x) . . . . 90° rotation
(x, y) ⇒ (-x, -y) . . . . 180° rotation
(x, y) ⇒ (y, -x) . . . . 270° rotation
Each successive rotation is a 90° rotation from the previous one. This makes writing the formulas in a spreadsheet really easy. The attached shows the transformed coordinates.
