Considered as a system of 2 inequalities, the graph is a quarter-plane area below line
Explanation:
We have to construct an intersection of two half-planes.
One is below (because of sign of inequality
graph{x-5 [-10, 10, -5, 5]}
Another - above (because of sign of inequality
graph{-x-4 [-10, 10, -5, 5]}
The intersection of these two areas is an East-oriented (towards the right hand side from a point of intersection of these two lines) quarter-plane, including its border.
