The equation is 

The equation is in slope-intercept form.

To graph the equation, first graph the .

                (Subtract x from each side)

                (Commutative property: )

                      (Additive inverse property: )

                        (Additive identity property: )

                    (Divide each side by  3)

                         (Cancel common terms)

           (Multiply each side by negative one)

                         (Product of two same signs is positive)

First find the y-intercept.

The y-intercept is the value of y, when .

                         (Substitute )

                               (Additive identity property: )     

                                 (Divide: )

Next find the x-intercept        

The co-ordinate point is

The x-intercept is the value of x, when .

                        (Substitute )

                (Multiply each side by 3)

                      (Cancel common terms)

                          (Zero product property: )

              (Add 9 to each side)

             (Commutative property: )

                       (Additive inverse property: )

                                   (Additive identity property: )

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.
