The equation is .

Rewrite the equation is .

To find the y-intercept, and x = 0.

                    (Substitute x = 0)

                                 (Apply zero product property: )

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

The coordinate point is (0, 4).

y-intercept is 4, So graph is (0, 4).

To find the x-intercept, and y = 0.

                          (Substitute y = 0)

                                (Apply zero product property: )

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

The coordinate point is (8, 0).

The above eqaution comparing  the slope-intercept form , Then m = , b = 4.

1) y-intercept is 4, So graph is (0, 4).

2) From (0, 4), move down 1 unit and right 2 units.

3) Draw a dot.

4) Draw a line through the points.

To graph the equation .

The solution of the graph eqution .
