You may have thought that this was a solution because, after substituting $\displaystyle{\left({4},-{2}\right)}\usepackage{cmbright}\Huge\$ for x and y and simplifying, you get $\displaystyle-{4}\usepackage{cmbright}\Huge\$ on both sides of the inequality. However, $\displaystyle-{4}>-{4}\usepackage{cmbright}\Huge\$ is a false statement, so $\displaystyle{\left({4},-{2}\right)}\usepackage{cmbright}\Huge\$ is not a solution. The correct answer is $\displaystyle{\left(-{3},{1}\right)}\usepackage{cmbright}\Huge\$ .
