Answer by dfrazzetto(277)   (Show Source): You can put this solution on YOUR website! y = 5x - 3 replace x with (x+3), plug back in: y = 5(x+3) -3 y = 5x + 15 -3 y = 5x + 12 y has increased by a net change of 15 overall, say if x was originally zero, y would have gone from -3 to 12, a net change of +15
