The equation is .

The equation is in slope-intercept form.

To graph the equation, first graph the .

           (Subtract 2.5x from each side)

           (Commutative property: a + b = b + a)

                                   (Additive inverse property: )

                            (Divide each side by 5)

                                 (Cancel common terms)

                                      (Divide: )

First find the y-intercept.

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

\ \

                                                     (Zero product property: )

Next find the x-intercept.

The co-ordinate point is (0, 15) \ \

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

                   (Multiply each side by 5)

                   (Additive identity property: 0 + a = a) \ \

                                                (Additive inverse property:)

                                          (Divide each side by 0.5)

                                                  (Cancel common terms)

                                                      (Divide: )

Next find the y-intercept.

The co-ordinate point is (30, 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.
