Question

What are the coordinates of the point (2, −3) after a counterclockwise rotation of 90° about the origin?

Answer 1

The rule for a 90* counterclockwise rotation around the axis is: (x,y) --> (-y,x) so your answer would be (2,-3) --> (3,-2)

Answer 2

(3,2) 90* rotation counterclockwise about the origin
