Answer

x-intercept=-10 y-intercept=20

Work Step by Step

4x-2y=-40 -2y=-4x-40 $\frac{-2y}{-2}$=$\frac{-4}{-2}$x+$\frac{-40}{-2}$ y=2x+20 Plug this rearranged equation into a graphing utility. From the produced graph you can see that the line crosses the x-axis when x=-10 and the y-axis when y=20.
