Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90ยฐ counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, โ6) is rotated 90ยฐ counterclockwise. (x, y) โ (โy, x) 1. switch the x- and y-coordinates: (6, โ3) 2. multiply the new x-coordinate by โ1: (6(โ1), โ3) 3. simplify: (โ6, โ3) .
