The linear equation is .

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

                (Substitute 0 for x)

                      (Apply additive identity property: 0 + 4 = 4)

The y-intercept is 4. The graph crosses the y-axis at (0, 4).

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

               (Substitute 0 for y)

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

    (Subtract 4 from each side)

          (Apply additive inverse property: )

          (Apply additive identity property: )

The x-intercept is . The graph crosses the x-axis at (, 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.
