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.

Apply subtraction property of equality: If a = b than a – c = b – c.

            (Subtract 1 from each side)

                        (Apply additive inverse property: 1 – 1 = 0)

                             (Subtract: 4 – 1 = 3)

The graph of the inequality is the shaded region and boundary of the inequality is

To draw inequality follow the steps.

1.   Draw a coordinate plane.

2.  Plot the points.

3.  Since inequality symbol is <, the boundary is not included in the solution set. Graph the boundary of the inequality with a dashed 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 .
