The equation .

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

                                   (Substitute x = 0)

                                            (Apply zero product property: )

y = 1                                                  (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)

                       (Add 3x to each side)

Apply commutative property of addition: a + b = b + a.

                                               (Apply additive inverse ptoperty: )

                                          (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 down 3 units and right 1 unit.

3) Draw a dot.

4) Draw a line through the points.

To graph the equation .
