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 zero product property: )

                               (Apply additive identity property: )

The y-intercept is 4.

The co-ordinate point is .

Next find the x-intercept.

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

                 (Substitute y = 0 in original equation)

Apply subtraction property of equality:If a = b then a c = b c.

      (Subtract 4 from each  side)

           (Apply additive inverse property: )

                 (Apply additive identity property: )

                    (Apply additive identity property: )

Apply multiplication property of equality: If a = b then a c = b c.

     (Multiply each side by negative 3)

                    (Cancel common terms)

                            (Multiply: )

The x-intercept is 12.

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.

For the graph using  x-intercept is 12 and y-intercept is 4 is
