5.1.2 Using Intercepts − Practice (continued)
5. Use intercepts to graph the line described by the equation 5 x − 5 y = 10.
6. Use intercepts to graph the line described by the equation 3 x + 2 y = 6.
7. Use intercepts to graph the line described by the equation 6 x − 9 y = 18.
8. Use intercepts to graph the line described by the equation − 2 x − 5 y = − 20.
9. Aneil wants to plant tomato plants and lettuce plants in a 60-square-foot garden. The tomato plants take up 2 square feet, and the lettuce plants take up 3 square feet. The equation 2 x + 3 y = 60 describes the number of tomato plants, x , and lettuce plants, y , that Aneil can plant in the garden. Graph this function and find the intercepts. What does each intercept represent?
