The graph is a region of the space on one side or another of the related function. If the inequality is strict then the related function itself is not part of the solution; otherwise it is.
x + 2y <12 2x + y < 10
The graph of an inequality is a region, not a line.

The Feasible Region
AB
An graph with an undefined region has a gap somewhere, where the function at that point is not valid. Usually there is a disjoint or a disconnect between the lines of the graph.

The region of zero electron density is called a "node."
