Incorrect. First determine which line is $\displaystyle{y}={3}{x}+{1}\usepackage{cmbright}\Huge\$ and which line is $\displaystyle{y}=-{x}+{2}\usepackage{cmbright}\Huge\$ . To determine the correct shading, test points on either side of each line to see which one makes the inequality true. The overlap region is the solution to the system. The correct answer is 4.
