If the parabola `y=(a-b)x^2+(b-c)x+(c-a)` touches x- axis then the line `ax+by+c=0` passes through a fixed point

If the parabola y=(a-b)x^2+(b-c)x+(c-a) touches x- axis then the line ax+by+c=0 (a) always passes through a fixed point (b) represents the family of parallel lines (c) is always perpendicular to x-axis (d) always has negative slope

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

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 a+b+c=0 the straight line 2ax+3by+4c=0 passes through the fixed point

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

If a,b,c in GP then the line a^(2)x+b^(2)y+ac=0 always passes through the fixed point
