Question

What are the coordinates of the point (-3,4) after a 270 degree rotation

Answer 1

(4,3)

You didn't list if it was clockwise or counterclockwise, so I will just assume that you were asking for clockwise.

Explanation:

If it is a 270 degree rotation cw, then it changes from (x,y) to (y,-x).

(-3,4) ---> (4,3)
