You need to substitute the values $\displaystyle{x}={1}\usepackage{cmbright}\Huge\$ and $\displaystyle{y}={2}\usepackage{cmbright}\Huge\$ into the two inequalities. Although (1, 2) is not a solution to the second inequality, you may not have noticed the first inequality is a greater than or equal to, so the first inequality is true for the point (1, 2).
