Undecidable problems | Logic in computer science | Computability theory
In computability theory and computational complexity theory, an undecidable problem is a decision problem for which it is proved to be impossible to construct an algorithm that always leads to a correct yes-or-no answer. The halting problem is an example: it can be proven that there is no algorithm that correctly determines whether arbitrary programs eventually halt when run. (Wikipedia).
Graphing the system of two linear inequalities with two horizontal line
