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 additive identity property: 0 + 7 = 7)

The y-intercept is 7, The co-ordinate point is (0, 7).

Next find the x-intercept.

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

                            (Substitute y = 0 in original equation)

                (Subtract 7 from each side)

                              (Additive inverse property: )

The x-intercept is , The y-intercept is 7, The co-ordinate point is (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.

The x-intercept is and y-intercept is 7.
