Question

Point P is rotated 180 degrees counterclockwise around the origin. What are the coordinates of the resulting point, P'? Point P is located at (-1, 6) to be specific.
A. (-1, 6)
B. (6, -1)
C. (-6, -1)
D. (1, -6)

Answer 1

A 180° rotation about the origin maps (x, y) to (−x, −y). For P(−1, 6), P' = (1, −6), so answer D.
