Correct. Looking at the graph, you see that the line $\displaystyle{y}={3}{x}-{1}\usepackage{cmbright}\Huge\$ intersects the region $\displaystyle{y}\ge-{2.5}\usepackage{cmbright}\Huge\$ , but does not lie completely inside it. Values of x that will make this inequality true include $\displaystyle{x}={0}\usepackage{cmbright}\Huge\$ and $\displaystyle{x}={2}\usepackage{cmbright}\Huge\$ ; when $\displaystyle{x}=-{2}\usepackage{cmbright}\Huge\$ , $\displaystyle{3}{x}-{1}\ge-{2.5}\usepackage{cmbright}\Huge\$ is not true.
