Answer:
(-1, 2)
Step-by-step explanation:
If we have a point (h,k) and it is rotated 90 degrees clockwise, the resulting point will have coordinates (k, -h).
So, basically the y coordinate becomes the x coordinate and x coordinate becomes the NEGATIVE of the y coordinate.
The point to rotate is (-2, -1), so after 90 degree clockwise rotation, it will become:
(-1, -(-2))
= (-1, 2)
This is the answer.
