The point C (-3,1) is rotated 90° clockwise about the origin. What are the coordinates of C’?

Question

D. (1,-3) this one
E. (1,3)
F. (3, -1)

Answer 1

To rotate a point clockwise 90° about the origin, we swap the x and y coordinates and change the sign of the new y-coordinate.

In this case, the original point C(-3,1) would become C' (1,-3). Therefore, the correct answer is D. (1,-3).
