Rewrite the equation below as a function of x.
y + 35x = 7.7
a. f(x) = -35x - 42.7
b. f(x) = 269.5x + 7.7
c. f(x) = 35x - 7.7
d. f(x) = -35x + 7.7

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) .
