Two lines meet at (A(-1,6)) on a graph. Which pair verifies this?एक ग्राफ में दो रेखाएं (A(-1,6)) पर मिलती हैं। कौन सा युग्म इसे सत्यापित करता है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (2x+y=4), (x-y=-7)(2x+y=4), (x-y=-7)
Substituting ((-1,6)) makes (2x+y=4) and (x-y=-7) both true. The intersection point must lie on both lines.((-1,6)) रखने पर (2x+y=4) और (x-y=-7) दोनों सही हैं। प्रतिच्छेद बिंदु दोनों रेखाओं पर होना चाहिए।
