    If the coordinates of the vertices of the triangle ABC be (-1, 6), (-3, -9), and (5, -8) respectively, then the equation of the median through C is

    A) \[13x-14y-47=0\]                   

    B) \[13x-14y+47=0\]

    C) \[13x+14y+47=0\]               

    D) \[13x+14y-47=0\]

    Correct Answer: C

    Solution :

     Required equation of median is \[y+8=\frac{-\frac{3}{2}+8}{-2-5}(x-5)\]                  \[\Rightarrow 13x+14y+47=0\].
