Please look in your text book for this problem Statement

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:  )

            (Divide each side by negative 4)

                    (Cancel common terms)

 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)

                       (Multiply:  )

                  (Divide each side by  3)

                       (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.

graph of the linear equatilon with intercepts 3x - 4y = 9

The x-intercept is and  y-intercept is .
