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.

The x-intercept is and  y-intercept is .
