the graph shows the cost of joining a gym in town a. the cost of joining a gym in town b is represented by a line parallel to the graph shown passing through (7,180). write an equation of the line that represents the cost of joining a gym in town b.

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) .
