If you substitute the rotation matrix for 180 degrees, you'd get the rule T180(x,y)=(x,y), so the rotated point should be (9,3)

^know that, or you become a lazy slob like me who imagined it on the coordinate plane instead of remembering the rule. (Facepalm)

You have a point. But to help someone, we need something concrete to work on.

I see nothing wrong with imagining it on a coordinate plane. The rule makes more since that way.
