यदि ग्राफ में दो रेखाओं का प्रतिच्छेद (\left\(-\frac{3}{2},4\right\)) है, तो कौन सा युग्म सही हो सकता है?
If the intersection of two lines on a graph is (\left\(-\frac{3}{2},4\right\)), which pair can be correct?
Explanation opens after your attempt
Correct Answer
A. (2x+y=1), \(x+2y=\frac{13}{2}\)
Concept
Substituting (\left\(-\frac{3}{2},4\right\)) makes both (2x+y=1) and \(x+2y=\frac{13}{2}\) true. The intersection point should be checked in both equations.
Why this answer is correct
The correct answer is A. (2x+y=1), \(x+2y=\frac{13}{2}\). Substituting (\left\(-\frac{3}{2},4\right\)) makes both (2x+y=1) and \(x+2y=\frac{13}{2}\) true. The intersection point should be checked in both equations.
Exam Tip
(\left\(-\frac{3}{2},4\right\)) रखने पर (2x+y=1) और \(x+2y=\frac{13}{2}\) दोनों सत्य हैं। प्रतिच्छेद बिंदु को दोनों समीकरणों में जांचना चाहिए।
