कौन-सा बिंदु \(4x+y\leq 12\) की सीमा रेखा पर है और प्रथम चतुर्थांश में भी है?

Which point lies on the boundary line of \(4x+y\leq 12\) and is also in the first quadrant?

Explanation opens after your attempt
Correct Answer

A. ((2,4))

Step 1

Concept

At ((2,4)), \(4\cdot2+4=12\), so it lies on the boundary. Exam tip: For boundary checking, replace the inequality by its equation.

Step 2

Why this answer is correct

The correct answer is A. ((2,4)). At ((2,4)), \(4\cdot2+4=12\), so it lies on the boundary. Exam tip: For boundary checking, replace the inequality by its equation.

Step 3

Exam Tip

((2,4)) पर \(4\cdot2+4=12\) इसलिए यह सीमा पर है। परीक्षा सुझाव: सीमा के लिए असमानता की जगह समीकरण लगाएँ।
