[" If "a,b,c" are in A.P.,then lines "ax+by+c=0" are "],[" concurrent at "]

If a, b, c are in A.P, then the lines ax+by+c=0

If a ,c,b are in G.P then the line ax+by+c=0

If a,c,b are in G.P then the line ax+by+c=0

If 4a,2b,c are in AP then lines 2ax+2bx=c are concurrent at

If a,b,c are in A.P then the lines represented by ax+by+c=0 are concurrent at the point

If a, c, b are in G.P then the line ax + by + c= 0

If a, b, c are in AP then ax + by +c=0 represents

Let for any three distinct consecutive terms a, b, c of an A.P, the lines ax by c = 0 be concurrent at the point P and Q (alpha, beta) be a point such that the system of equations x y z = 6 2x 5y alpha z = beta and x 2y 3Z = 4 , has infinitely many solutions. Then (PQ)^2 is equal to ________.

If a, b, c are in A.P, the lines ax+by+c=0 pass through the fixed point

If 4a+5b+c=0 then the set of lines ax+by+c=0 are concurrent at the point
