The equation is .

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

                    (Substitute x = 0)

                                 (Apply zero product property: )

                                   (Apply addititve identity property: )

The coordinate point is (0, ).

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

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

                        (Substitute y = 0)

Apply addition property of equality: If a = b then a + b = b + a.

  (Add to each side)

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

                        (Apply additive inverse property: )

                              (Apply additive identity property: )

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

                     (Multiply each side by 3)

                               (Cancel common terms)

                                    (Multiply: )

The coordinate point is .

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

1) y-intercept is 3, So graph is (0, 3).

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

3) Draw a dot.

4) Draw a line through the points.

To graph the equation .

The solution of the graph eqution .
