Add 2 to both sides: $\displaystyle{c}-{2}+{2}>-{5}+{2}\usepackage{cmbright}\Huge\$ , so $\displaystyle{c}>-{3}\usepackage{cmbright}\Huge\$ . The numbers greater than $\displaystyle-{3}\usepackage{cmbright}\Huge\$ are represented by points to the right of $\displaystyle-{3}\usepackage{cmbright}\Huge\$ , as shown in the graph.
