rotate on graph

Question

Point T has coordinates (2,5). If you rotate T 270° about the​ origin, (0,0), what are the coordinates of T′​?

Answer 1

With a 270 degree rotation (assuming it is a counterclockwise rotation) the coordinate rule states that (x,y) becomes (y, -x).

In this case (2,5) would become (5, -2)
