2y + 3x = 2 Let's convert to slope-intercept form (y=mx+b) to find the slope. Move x to the right side. 2y = -3x + 2 Divide by the y coefficient. (2) y = -3/2x + 1 In slope-intercept form, (y=mx+b) the slope is represented as m. In this case the slope is -3/2. Parallel lines have the same slope. Since m(AB) = -3/2, m(CD) = -3/2, too.
