If the solution set of a system of linear inequalities in two variables is non-empty, what type of set must it necessarily be?

Answer and explanation

Correct answer: A convex set

Each linear inequality represents a half-plane, and every half-plane is convex. The intersection of half-planes remains convex, so option A is correct. Exam tip: a convex solution region need not be bounded.
