The equation is .

First find the y-intercept.

The y-intercept is the value of y, when x = 0.

                                 (Substitute x = 0 in original equation)

                                    (Apply Additive inverse property: a + 0 = a)

                              (Divide each side by negative 4)

                                      (Cancel common terms)

                                    (Divide: )

The y-intercept is , so the graph intersects the y-axis at (0, ).

Next find the x-intercept.

The x-intercept is the value of x, when y = 0.

                             (Substitute y = 0 in original equation)

                                        (Apply Additive inverse property: a + 0 = a)

The x-intercept is 18, so the graph intersects the x-axis at ( 18 , 0).

Graph Using Intercepts:

Use these ordered pairs to graph the equation.

1.     Draw a coordinate plane.

2.     Plot the points.

3.     Draw a line through these points.
