Question

What are the coordinates of the image of P(-2,5)

after a clockwise rotation of 90° about the origin?

Answer 1

5,2

Explanation:

Clockwise rotations for 90 is

The preimage of (x,y), or for this problem, (-2,5) into (y,-x).

So, a clockwise rotation is from x,y into y,-x

So we do -2,5 into 5,2

We flipped the x and y, and the 2 became positive because two negatives equal a positive
