Answer: M'=(-2,3)
Explanation:
Rotation of point through 90° about the origin in anticlockwise direction when point M (h, k) is rotated about the origin O through 90° in anticlockwise direction. The new position of point M (h, k) will become M' (-k, h).
For this h=3, and k=2 so the new point will be M'=(-2,3)
