Answer by Ave(106)   (Show Source): You can put this solution on YOUR website!5x+4y ≥ 20 set x equal to 0 to find y intercept 4y≥20 y≥5 (0,5) ---- 5x+4y ≥ 20 set y equal to 0 to find x intercept 5x≥20 x≥4 (4,0) ---- plot the points and draw a Solid line through them. (0,0) would make the equation false so shade the opposite side that (0,0) falls on. The right side.
