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: )

The y-intercept is 4.

The co-ordinate point is (0, 4)

Next find the x-intercept.

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

                               (Substitute y = 0 in original equation)

                                     (Apply additive identity property: )      

                                (Divide each side by 4)

                                        (Cancel common terms)

The x-intercept is 1

The co-ordinate point is (1, 0) \ \

Use these ordered pairs to graph the equation.

1.     Draw a coordinate plane.

2.     Plot the points.

3.     Draw a line through these points.

The x-intercept is 1 and y-intercept is 4.
