You may have been thinking about the solution to a system of equations. An ordered pair is a solution to a system of inequalities if it satisfies both inequalities. You need to substitute the values $\displaystyle{x}={1}\usepackage{cmbright}\Huge\$ and $\displaystyle{y}=-{1}\usepackage{cmbright}\Huge\$ into the two inequalities to see if they are true.
