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 identity property: )

    (Multiply each side by negative one)

                      (Product of two same signs is positive)

The y-intercept is 8 , 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)

                  (Apply additive identity property: )

The x-intercept is 8 , so the graph intersects the x-axis at .

 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.  

 x-intercept is 8 and  y-intercept is 8.
