    vectors help- shortest distance

    Find the shortest distance from the point (0,1,6) to the line that passes
    through the two points (-1,1,4) and (1,0,5).
    \


    am not sure what equation to use?

     r = r_{0} + \lambda t ?

    If $\ell: P+tD$ is a line and $X$ is a point the the distance from the point to the line is:

    $D(\ell;X)=\dfrac{\|\overrightarrow {PX}\times D\|}{\|D\|}$
