## Introductory Algebra for College Students (7th Edition)

2x+3y=30 2x-2x+3y=-2x+30 3y=-2x+30 $\frac{3y}{3}$=-$\frac{2}{3}$x+$\frac{30}{3}$ y=-\$\frac{2}{3}x+10 Plug this rearranged equation into a graphing utility. From the produced graph you can see that the line crosses the x-axis when x=15 and the y-axis when y=10.
