In which of the scenarios can you reverse the dependent and independent variables while keeping the interpretation of the slope meaningful?

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) .

Find the slope and the y-intercept if there's one and the equation of the line given these two points( 3, 2) and( 3, -4)
