The linear function is .

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

                           (Substitute 0 for x)

Apply addition property of equality: if a = b than a + c = b + c.

               (Add 2 to each side)

                     (Apply Additive inverse property: )

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

                          (Multiply each side by negative one)

                                    (Product of two same signs is positive)

The y-intercept is 2. The graph crosses the y-axis at (0, 2).

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

                          (Substitute 0 for y)

Apply addition property of equality: if a = b than a + c = b + c.

              (Add 2 to each side)

                    (Apply Additive inverse property: )

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

The x-intercept is 2. The graph crosses the x-axis at (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.

x-intercept is 2 and the y-intercept is -2.
