Let L be the line with parametric equations

x = -1+3t
y = −5−t
z = −1

Find the shortest distance d from the point P0=(−5, −3, 5) to L, and the point Q on L that is closest to P0. Use the square root symbol '√' where needed to give an exact value for your answer.
d = _
Q = (_, _, _)

I know we have to deal with them in vectors. I think we should be making a vector that is LQ but otherwise idk what to do. If someone could help that would be great.
