If the intersection of two lines on a graph is \(\left(\frac{5}{2},-\frac{3}{2}\right)\), which pair can be correct?यदि ग्राफ में दो रेखाओं का प्रतिच्छेद \(\left(\frac{5}{2},-\frac{3}{2}\right)\) है, तो कौन सा युग्म सही हो सकता है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(2x+y=\frac{7}{2}\), \(x-2y=\frac{11}{2}\)\(2x+y=\frac{7}{2}\), \(x-2y=\frac{11}{2}\)
Substituting \(\left(\frac{5}{2},-\frac{3}{2}\right)\) makes both \(2x+y=\frac{7}{2}\) and \(x-2y=\frac{11}{2}\) true. Check the intersection point in both equations.\(\left(\frac{5}{2},-\frac{3}{2}\right)\) रखने पर \(2x+y=\frac{7}{2}\) और \(x-2y=\frac{11}{2}\) दोनों सत्य हैं। प्रतिच्छेद बिंदु को दोनों समीकरणों में जांचें।
