Which is the correct graphical representation of the inequality \(2x-3y>6\)?

Answer and explanation

Correct answer: The boundary \(2x-3y=6\) is dashed and the half-plane below it is shaded.

Rewriting gives \(y<\frac{2}{3}x-2\), so the required region lies below the boundary line. Since the inequality is strict, the boundary is dashed, not solid. Exam tip: reverse the inequality sign when dividing by a negative number.
