JEE Main 2005Annual, Paper 1MathematicsEasyCoordinate Geometry478× since 2002If non zero numbers a,b,ca, b, ca,b,c are in H.P.,H.P.,H.P., then the straight line xa+yb+1c=0{x \over a} + {y \over b} + {1 \over c} = 0ax+by+c1=0 always passes through a fixed point. That point is :AOption A. (−1,2)(-1,2)(−1,2)BOption B. (−1,−2)(-1, -2)(−1,−2)COption C. (1,−2)(1, -2)(1,−2)DOption D. (1,−12)\left( {1, - {1 \over 2}} \right)(1,−21)CheckSkip · show solution
