    The equation of the plane which bisects the line joining (2, 3, 4) and (6, 7, 8) is:

    A)  \[x-y-z-15=0\]

    B)  \[x-y+z-15=0\]

    C)  \[x+y+z-15=0\]

    D)  \[x+\text{ }y+\text{ }z+15=0\] 

    E)  \[x-y-z+\text{ }15=0\]

    Correct Answer: C

    Solution :

    \[\because \]Midpoint of line joining (2, 3,4) and (6, 7,8) is (4, 5, 6) this point is satisfied by one equation \[x+y+z-15=0\] \[\therefore \]\[x+y+z-15=0\]is required equation of plane.
