Which statement is correct about the graph of the linear inequality \(ax+by<c\) in two variables, where \(a\) and \(b\) are both non-zero?

Answer and explanation

Correct answer: An open half-plane excluding the boundary line

\(ax+by=c\) is the boundary line. Since the sign is \(<\), points on this line do not satisfy the inequality, so the solution is an open half-plane on one side. Exam tip: draw a dashed boundary for \(<\) or \(>\).
