If the line ax+by+c=0 always passes through the fixed point (1,-2) then : a,b,c are in

If the straight line ax + by + c =0 always passes thorugh ( 1, - 2) , then a,b,c, are in :

If a+b+c=0 then the line 3ax+by+2c=0 passes through the fixed point

If |{:(a,b-c,c+b),(a+c,b,c-a),(a-b,a+b,c):}|=0 the line ax +by +c=0 passes through the fixed point which is

If the straight line ax+by+c=0 always passes through (1, -2), then a, b, c are in:

If the straight line ax +by+c=0 always passes through (1,-2) then a,b,c are in

If 5a+4b+20c=t,then the value of t for which the line ax+by+c-1=0 always passes through a fixed point is

If 3a+2b+4c=0 then the lines ax+by+c=0 pass through the fixed point

If 3a+2b+4c=0 then the lines ax+by+c=0 pass through the fixed point

If 3a+2b+c=0 the family of straight lines ax+by+c=0 passes through the fixed point (p, q) then p + q
