Answer:
90° rotation about the origin (clockwise) -- (4,3)
90° rotation about the origin (counterclockwise) -- (-4,-3)
Step-by-step explanation:
You did not specify clockwise rotation or counterclockwise rotation. I will show for both.
Given a point (h,k):
1. Rotation 90° about origin clock wise will make it (k, -h). You basically swap x and y and make the y change signs
2. Rotation 90° about origin counterclockwise will make it (-k,h). You basically swap x and y and make x change signs
Thus, for the point given as (-3,4):
1. Rotation 90° about origin clock wise will make it (4,3), and
2. Rotation 90° about origin counterclockwise will make it (-4,-3)
