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 should substitute the values $\displaystyle{x}={1}\usepackage{cmbright}\Huge\$ and $\displaystyle{y}={2}\usepackage{cmbright}\Huge\$ into the two inequalities to see if they are true. The point of intersection of these boundary lines is at (1, 2) not at (2, 1).
