I just want a guide on how to begin to solve, I dont want the answer.Answer by richwmiller(9135)   (Show Source): You can put this solution on YOUR website!These equations are in standard form ax+by=c not slope intercept form y=mx+b In this form the slope is -a/b the slope of the first is -3/7 the second -1/2 if they were parallel they would be the same if they are perpendicular the product of the two slopes would be -1 they are neither.
