The related boundary line of $\displaystyle{y}<-{x}\usepackage{cmbright}\Huge\$ is $\displaystyle{y}=-{x}\usepackage{cmbright}\Huge\$ . This line has a slope of $\displaystyle-{1}\usepackage{cmbright}\Huge\$ and goes through (0, 0). Because the boundary line is not included in the solution, it is a dashed line. The ordered pair (0, $\displaystyle-{1}\usepackage{cmbright}\Huge\$ ), for example, is a solution. Therefore, the shaded region will be below the line.
