Question

what will be the coordinates of N after a 90° counterclockwise rotation around the origin A (-7, -3) B (-7, 0) C (3, 7) D (-3, -7)

Answer 1

(- 7, - 3)

Explanation:

Under a counterclockwise rotation about the origin of 90°

a point (x , y) → (- y, x ), hence

N(- 3, 7) → N'(- 7, - 3)

Answer 2

It's A. If you imagine the box swining towards the left, the bottom left corner will be at (-7, -3)
