What are coordinates of P' if point P(-5, -3) is rotated 90° counterclockwise?

What are coordinates of P' if point P(-5, -3) is rotated 90° counterclockwise?

Explanation

When rotating a point (x, y) 90° counterclockwise, the new coordinates are (-y, x).

For P(-5, -3), the new coordinates P' will be (3, -5).
