    The equation of a line through the point (1, 2) whose distance from the point (3, 1) has the greatest value, is

    A)  \[y=2x\]                             

    B)  \[y=x+1\]

    C)  \[x+2y=5\]     

    D)         \[y=3x-1\]

    E)  \[y=x+7\]

    Correct Answer: C

    Solution :

    For the greatest distance, both points Fe on a straight line. \[\therefore \]Required equation of line is \[y-2=\frac{1-2}{3-1}(x-1)\] \[\Rightarrow \]               \[2y-4+x=1\] \[\Rightarrow \]               \[x+2y=5\]
