Andrew’s rotation maps point M(9, –1) to M’(–9, 1). Which describes the rotation? 180 degrees rotation 270 deg

Question

Andrew’s rotation maps point M(9, –1) to M’(–9, 1). Which describes the rotation?
180 degrees rotation
270 degrees clockwise rotation
90 degrees counterclockwise rotation     
90 degrees clockwise rotation

GPT-5 mini · Answer

180 degrees rotation

Reason: A 180° rotation about the origin sends (x,y) to (−x,−y). For (9,−1) this gives (−9,1), which matches M′.
