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.
