9-152.

On graph paper, graph the system of equations at right. Then state the solution to the system. If there is not a solution, explain why not.

$\left. \begin{array} { l } { y = - \frac { 2 } { 5 } x + 1 } \\ { y = - \frac { 2 } { 5 } x - 2 } \end{array} \right.$

Why is there no solution? How can you tell by looking at the equations?

Use the eTool below to graph the equations.
