The following triangle fox is transformed using a rotation: triangle fox is shown. f is at negative 1, 1, o is at negative 2, 3, x is at negative 3, 0. which could be coordinates of f'o'x' after the rotation? (4 points)

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .
