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

To draw boundary of the equality follow the simple steps.

1.   Draw a coordinate plane.

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

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

Substitute x = 0 and y = 0 in original inequality .

The statement is false.

4.  Since the statement is false, shade the region that do not contains point .

Inequality graph is
