The linear function is .

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

                   (Substitute 0 for x)

                             (Apply zero product property: )

                               (Apply additive identity property: )

The y-intercept is 5. The graph crosses the y-axis at (0, 5).

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 5 to each side)

                     (Apply Additive inverse property: )

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

Apply division property of equality: if a = b than .

                            (Divide each side by 3)

                                 (Cancel common terms)

                       (Multiply each side by negative one)

                                 (Product of two same signs is positive)

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.

x-intercept is and the y-intercept is 5.
