Answer:
(2, 8)
Explanation:
You want the image coordinates of (8,-2) after 90 degree counterclockwise rotation.
90° Rotation
The transformation of (x, y) coordinates that does a 90° CCW rotation about the origin is ...
(x, y) ⇒ (-y, x)
Application
Applying this transformation to the given point, we have ...
(8, -2) ⇒ (2, 8)
The rotated point is (2, 8).
