 PAGE: 325 SET: Exercises PROBLEM: 1  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 . TESTIMONIALS
