The Solution:
Given the system of inequalities below:

Graphing the inequalities, we have:
To choose the type of boundary line for the inequalities.


Enter two points on the boundary line.
For the inequality x>4:

For the second inequality, two points on the boundary line are:

The region to be shaded is region B as shown in my graph above (though I do not know how A and B are labeled in the given graph)
