Question

This section contains 1 Assertion-Reason type question, which has 4 choices (A), (B), (C) and (D) out of which ONLY ONE is correct.
A : The graph of the equations (x + y) P + (xy) Q + 2 = 0 and (x + y) P + (yx) Q + 4 = 0 (where P and Q are non zero real numbers) intersect at a point.
R : Two lines a1x + b1y + c1 = 0 and a2x + b2y + c2 = 0 (where a1, a2, b1 and b2 are non-zero real numbers) are intersecting if a1a2=b1b2.

इस खण्ड में 1 कथन-कारण प्रकार का प्रश्न है, जिसमें 4 विकल्प (A), (B), (C) तथा (D) दिये गये हैं, जिनमें से केवल एक सही है।
A : समीकरणों (x + y) P + (xy) Q + 2 = 0 तथा (x + y) P + (yx) Q + 4 = 0 (जहाँ PQ अशून्य वास्तविक संख्याएँ हैं) के ग्राफ एक बिंदु पर प्रतिच्छेद करते है।
R : दो रेखाएँ a1x + b1y + c1 = 0 तथा a2x + b2y + c2 = 0 (जहाँ a1, a2, b1 तथा b2 अशून्य वास्तविक संख्याएँ हैं) प्रतिच्छेद करती है, यदि a1a2=b1b2
