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)

                         (Zero product property: )

                              (Subtract: )

The y-intercept is 4.

The co-ordinate point is

Next find the x-intercept.

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

                    (Substitute y = 0 in original equation)

          (Subtract 4 from each  side)

               (Apply Additive inverse property: )

                     (Apply Additive identity property: )

                        (Subtract: )

          (Multiply each side by negative 3)

                         (Cancel common terms)

                                 (Multiply: )

The x-intercept is 12.

The co-ordinate point is

Use these ordered pairs to graph the equation.

1.     Draw a coordinate plane.

2.     Plot the points.

3.     Draw a line through these points.

For the graph using  x-intercept is 12 and y-intercept is 4 is
