The coordinates of the image are (4,-1). 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 F(3, -6) is rotated 180° counterclockwise around the origin. What are the coordinates of the resulting point, F'?Solution: (, )
