A variable line intersects co-ordinate axes at two points A and B. If the area of traingle OAB (where 'O' is origin) is 4 square units, then the locus of middle point of AB is- (1)xy = 2 (2)|xy| = 2 (3)x2?+ y2?= 4 (4)x2?? y2?= 4 Experts the correct answer is option 2 . I'm not getting why the answer with modulus is correct and not option 1 . Please clarify my doubts in detail. Share with your friends Share 1 Aamish Samotra answered this 1 View Full Answer
