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

Question

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

Answer 1

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

So, the x-coordinate of C' will be the y-coordinate of C, and the y-coordinate of C' will be the opposite sign of the x-coordinate of C.

Therefore, the coordinates of C' will be (1,-3).

The correct answer is D. (1,-3).
