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)

                  (Multiply:  )

     (Multiply each side by negative one)

              (Product two same signs is positive)

                  (Product two different signs is negative)

The y-intercept is , so the graph intersects the y-axis at .

Next find the x-intercept.

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

              (Substitute y = 0 in original equation)

                    (Apply Additive identity property: )

               (Divide each side by 7)

                     (Cancel common terms)

                          (Divide: )

The x-intercept is , so the graph intersects the x-axis at.

Graph Using Intercepts:

Use these ordered pairs to graph the equation.

1.     Draw a coordinate plane.

2.     Plot the points.

3.     Draw a line through these points.

 x-intercept is and  y-intercept is .
