If the intersection of two lines on a graph is \(\left(-\frac{3}{2},4\right)\), which pair can be correct?यदि ग्राफ में दो रेखाओं का प्रतिच्छेद \(\left(-\frac{3}{2},4\right)\) है, तो कौन सा युग्म सही हो सकता है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(2x+y=1\), \(x+2y=\frac{13}{2}\)\(2x+y=1\), \(x+2y=\frac{13}{2}\)
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.\(\left(-\frac{3}{2},4\right)\) रखने पर \(2x+y=1\) और \(x+2y=\frac{13}{2}\) दोनों सत्य हैं। प्रतिच्छेद बिंदु को दोनों समीकरणों में जांचना चाहिए।
