Question

What is the coordinate for the image of point H(2, –6) under a 90° clockwise rotation about the origin?
H’(–6, –2)
H’(6, –2)
H’(–6, 2)
H’(6, 2)

Answer 1

A 90° clockwise rotation about the origin sends (x,y) to (y, −x). Applying this to H(2, −6) gives H' = (−6, −2). So the correct choice is H'(−6, −2).
