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

                   -----------------------> (Equation 1)

               -----------------------> (Equation 2)

Graph the equations and find the intersection point.

The graphs appear to intersect at (0, –4).

Check:

To check the solution by substituting the coordinates in each equation.

Substitute (0, –4) in equation 1.

                          (Apply zero product property: )

                            (Apply additive identity property: 0 – 4 = –4)

The statement is true.

Substitute (0, –4) in equation 2.

                          (Apply zero product property: )

                            (Apply additive identity property: 0 – 4 = –4)

The statement is true.

The solution of the system is (0, –4).
