The graph of the inequality is the shaded region and boundary of the inequality is . To graph the boundary, find the x-intercept and y-intercept of the line.

First find the y-intercept.

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

                           (Substitute x = 0 in original equation)

                                    (Simplify)

                 (Add 10 to each side)

                                         (Simplify)

                                   (Divide each side by negative 5)

                                              (Simplify)

The y-intercept is – 2, so the graph intersects the y-axis at (0, – 2).

Next find the x-intercept.

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

                           (Substitute y = 0 in original equation)

                                       (Simplify)

                      (Add 10 to each side)

                                              (Simplify)

                                        (Divide each side by 4)

                                               (Simplify)

The x-intercept is 2.5 , so the graph intersects the x-axis at (2.5, 0).

To draw inequality follow the steps.

1.   Draw a coordinate plane.

2.  Plot the points.

3.  Since inequality symbol is , the boundary is included in the solution set. Graph the boundary of the inequality with a solid line.

4.  To determine which half-plane to be shaded use a test point in either half-plane. A simple choice is .

Substitute and y = 0 in original inequality .

The statement is true.

4.  Since the statement is true, shade the region that contains point .
