Answer

a) x + y = -1 b) x - y = -5

Work Step by Step

writing equation in slope intercept form: x + y = 7 y = -x + 7 So, the slope is -1. a) line parallel to x + y = 7 and passing through point (-3,2) (y - 2)/(x +3) = -1 x + y = -1 b) line perpendicular to x + y = 7 and passing through point (-3,2) will have slope 1 (y - 2)/(x +3) = 1 x - y = -5
