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 multiplication property of zero: )

The y-intercept is 4. 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 subtraction property of equality: Subtract 4 from each side.

Apply commutative property of addition: .

                           (Apply additive inverse property: )

Apply division property of equality: Divide each side by 2.

                           (Cancel common terms)

                             (Divide: )

The x-intercept is , so the graph intersects the x-axis at .

Use these ordered pairs to graph the equation.

1.     Draw a coordinate plane.

2.     Plot the points.

3.     Draw a line through these points.
