Answer:

(-1, 2)

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.
