Two lines meet at (A(2,-5)) on a graph. Which pair verifies this?एक ग्राफ में दो रेखाएं (A(2,-5)) पर मिलती हैं। कौन सा युग्म इसे सत्यापित करता है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (3x+y=1), (x-y=7)(3x+y=1), (x-y=7)
Substituting ((2,-5)) makes (3x+y=1) and (x-y=7) both true. The intersection point must lie on both lines.((2,-5)) रखने पर (3x+y=1) और (x-y=7) दोनों सही हैं। प्रतिच्छेद बिंदु दोनों रेखाओं पर होना चाहिए।
