The boundary lines $\displaystyle{y}=-{1}\usepackage{cmbright}\Huge\$ , $\displaystyle{y}={2}\usepackage{cmbright}\Huge\$ are shown as solid lines, thus the $\displaystyle\le\usepackage{cmbright}\Huge\$ symbol. The boundary line $\displaystyle{y}={3}{x}-{4}\usepackage{cmbright}\Huge\$ is shown as a dashed line, thus the $\displaystyle>\usepackage{cmbright}\Huge\$ symbol. However, the points in the shaded region do not satisfy $\displaystyle{y}>{3}{x}-{4}\usepackage{cmbright}\Huge\$ . Be sure to test a point from the shaded region in each inequality.
