The expression is .

The equation is in slope-intercept form y = mx + c.

To graph the equation, first graph the .

According to subtraction property of equality: if , then .

      (Subtract 3x from each side)

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

                       (Additive inverse property: )

                  (Divide each side by 0.5)

                          (Cancel common terms)

First find the y-intercept.

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

                        (Zero product property: )

                          (Additive identity property: )

y = 12                              (Divide: )

Next find the x-intercept

The co-ordinate point is

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

      (Multiply each side by 0.5)

                  (Cancel common terms)

                            (Zero product property: )

          (Add 3x to each side)

                            (Additive inverse property: )

                                  (Additive identity property: )

According to division property of equality: if , then .

                             (Divide each side by 3)

                                  (Cancel common terms)

x = 2                                     (Divide: )

Next find the y-intercept.

The co-ordinate point is (2, 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.
