Write an equation of a line parallel to line EF in slope-intercept form that passes through point (2, -6)

Which equation represents a proportional relationship that has a constant of proportionality equal to 1/5

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) .

I’m stuck on this equation, anyone got the answer?
