Let L be the line belonging to the family of straight lines (a+2b) x+(a-3b)y+a-8b =0, a, b `in `R, which is the farthest from the point (2, 2). If L is concurrent with the lines x-2y+1=0 and `3x-4y+ lambda=0`, then the value of `lambda` isA. 2B. 1C. -4D. 5

Answer» Correct Answer - D
Lines x+4y+7 =0 and x-2y+1 =0 intersect at (-3, -1) which must satisfy the line `3x-4y+lambda=0. "Then " -9+4+lambda=0 " or " lambda = 5.`
