Hi, Im doing a college course in geometry, and i have a proofs question, can somebody please solve this for me. I would really appreciate it. They have to be in a 2 column format. Thank you.

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) .

What does the sign of the slope tell you about a line?
