Which statement is correct about point ( (4,2) ) for (2x+y>10)?

Answer and explanation

Correct answer: It lies on the boundary line but is not included in the solution

Substituting
(4,2) gives
\(2(4)+2=10\). Hence, the point lies on the boundary line \(2x+y=10\). Since the inequality uses \(>\), equality is not included, so this point is not part of the solution region. Option B is incorrect because it includes equality. Exam tip: For strict inequalities, \(>\) and \(<\), points on the boundary line are excluded.
