If the point ((2,k)) is a solution of both \(x+3y<11\) and \(y-x\geq 1\), what is the conclusion for (k)?

Answer and explanation

Correct answer: No such \(k\) exists

Substituting \((2,k)\) into the first inequality gives \(2+3k<11\), so \(k<3\). The second inequality gives \(k-2\geq1\), so \(k\geq3\). No number can be both less than \(3\) and at least \(3\); hence, no such \(k\) exists. Although \(k=3\) is a close distractor, it fails the strict condition \(k<3\). Exam tip: substitute the point into each inequality separately and then check the intersection of the resulting conditions.
