Rotations: Find the coordinates

If Q is mapped onto Q'(4,2) under a 90º anticlockwise rotation about C(-1,3), find the coordinates of Q.

Q is the image of Q'(4,2) under a 90º clockwise rotation about (-1,3).

The coordinates of Q are (-2,2)

The point Q(-2, -3) is rotated 180 counterclockwise around the origin. What are the coordinates of the resulting point, Q'?

Solution: (, )
