Mira uses the mapping rule to find the coordinate of a point that had been rotated 90° clockwise about the origin. examine mira’s solution to determine which step has an error. m(–5, –6) is rotated 90° clockwise. step 1. use the rule (x, y)g(y, –x). step 2. switch x and y coordinates: (–6, –5) step 3. multiply the new x-coordinate by –1: ((–1)–6, –5) step 4. simplify: (6, –5)
