[" The point of concurrence of "],[" the lines "],[(a+2b)x+(a-b)y+(a+5b)=0" is "]

The point of concurrence of the lines (2a+5b)x+(3a-2b)y-5a-3b=0 is

If a,b,c are in Hp. (a,b,c!=0 point of concurrence of family of lines x/a+y/b+1/c=0 is

If a^(2)+4b^(2)-9c^(2)=4ab, then the line on which the point of concurrency of family of straight line ax+by+3c=0 lies is (a)x+y=-1(c)x+y3(b)x+y=1 (d) 2x+y=0

For all the values of 'a' and 'b',the lines (a+2b)x+(a-b)y+(a+5b)=0 passes through the point

Locus of the image of a point A(0,0) in the line (2a+b)x+(3a-2b)y+(b-5a)=0 is (where a and b are parameters).

The family of lines (2 cos theta + 3 sin theta) x + (3 cos theta - 5 sin theta) y-(5 cos theta - 2 sin theta) = 0 is concurrent at (x_1, y_1) and the family of lines (a+2b) x+(a-3b) y+b-a=0 for different values of a and b is concurrent at (x_2, y_2) then : (A) x_2 + y_2 = x_1 (B) x_2 + y_2 = y_1 (C) 6x_2 + y_2 = 2x_1 + y_1 (D) none of these

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 lines x-2y+1=0 and 3x-4y+lambda =0 , then the value of lambda is

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 is
