Question

what are the coordinates of the point (-10, -3) after a 180 degree clockwise rotation about the origin?

Answer 1

The coordinates of the point (-10, -3) after a 180 degree clockwise rotation about the origin will be (10, 3).

As, we have a point which is in negative side after we turn it clockwise direction it will move to positive side so the coordinates will become positive.

Answer 2

The coordinates would be (10, 3) 

If you plot these points and rotated 180 degrees, you get the same axes only all positives become negatives and vice versa.
