If `a , b ,c` are in harmonic progression, then the straight line `((x/a))+(y/b)+(l/c)=0` always passes through a fixed point. Find that point.

If a,b,c are non-zero real numbers in H.P then the line (x)/(a)+(y)/(b)+(1)/(c)=0 always passes through a fixed point whose coordinates are

If A, B and C are in AP, then the straight line Ax + 2By+C =0 will always pass through a fixed point. The fixed point is

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

If a,b and c are in AP, then the straight line ax+by+c=0 will always pass through a fixed point whose coordinates are

If a and b are two arbitrary constants,then prove that the straight ine (a-2b)x+(a+3b)y+3a+4b=0 will pass through a fixed point.Find that point.
