The equation is .

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

                             (Substitute x = 0)

                                   (Apply zero product property: )

                                         (Apply addititve identity property: 0 + 1 = 1)

The coordinate point is (0, 1).

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

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

                                (Substitute y = 0)

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

                    (Subtract 1 from each side)

                                   (Apply additive inverse property: )

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

                              (Divide each side by 3)

                                  (Cancel common terms)

The coordinate point is .

The above eqaution comparing  the slope-intercept form , Then m = 3, b = 1.

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

2) From (0, 1), move up 3 unit and right 1 unit.

3) Draw a dot.

4) Draw a line through the points.

To graph the equation .

The solution of the graph eqution .
