For the inequality \(x+y\leq 7\), which statement is true in the origin test?

Answer and explanation

Correct answer: \(0\leq 7\) is true

Substituting the origin \,\((0,0)\) into the inequality gives \(0+0\leq 7\), or \(0\leq 7\), which is true. Therefore, the solution region lies on the side containing the origin. Option B incorrectly reverses the inequality sign. Exam tip: In graphing a linear inequality, choose a test point that does not lie on the boundary line.
