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 multiplication property of zero: )

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

Next find the x-intercept.

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

                           (Substitute y = 0 in original equation)

               (Add 3 to each side)

                                (Apply additive inverse property: )

                        (Multiply each side by 4)

                                 (Cancel common terms)

                                   (Multiply: )

The x-intercept is 12, so the graph intersects the x-axis at ( 12, 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.
