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) .

[10 points, algebra 2]according to my answer key the restrictions are -1 and 4. but why not positive 1?

2. explain in words how you plot the point (4, −2) in a rectangular coordinate system.
