Answer

Please see the graph.

Work Step by Step

Green line: $x-y>2$ $x-y>2$ $x-y+y-2>2+y-2$ $x-2>y$ Let's use $(0,0)$ to see if this point is a solution of the graph. $x-2>y$ $0-2>0$ $-2>0$ (false) $(0,0)$ is not a solution of the graph, so we'll shade the other side of the line. Red line: $y<5$ Let's use $(0,0)$ to see if this point is a solution of the graph. $y<5$ $0<5$ (true) $(0,0)$ is a solution of the graph, so we shade that side of the line. The union of the two lines is where the graph is shaded either red or green.
