Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90Β° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, β6) is rotated 90Β° counterclockwise. (x, y) β (βy, x) 1. switch the x- and y-coordinates: (6, β3) 2. multiply the new x-coordinate by β1: (6(β1), β3) 3. simplify: (β6, β3) .
