Write the each equation in slope-intercept form y = mx + b.

Graph the equations and find the intersection point.

The graphs appear to intersect at (–9, 3).

Check the solution:

Check the solution by substituting the coordinates in each equation.

Substitute (–9, 3) in equation 1.

.                  The statement is true.

Substitute (-9, 3) in equation 2.

.                         The statement is true.

The solution of the system is (–9, 3).
