How do I find the shortest distance between the two lines (x, y, z) = (-2, -1, - 4) + t(1, 1, -1)
and
(x,yz)=(−1−11)+t(31−2)
Find the distance between the point $\displaystyle (-2,-1,-4)$ and the plane that contains the point $\displaystyle (-1,-1,1)$ with normal $\displaystyle <1,1,-1>\times <3,1,-2>$.
