Vectors watch

1. Can anyone help me with this question please. It's the "parallel" bit that I'm finding confusing:

A thin pipe, U, runs directly below and parallet to the y-axis at a depth of 2m below ground level which can be taken to be the xy-plane.

Write down a vector equation for the line representing the pipe U.

Write down a vector equation for the line representing the pipe U.
r = (0,0,-2) +t(0,1,0)

Parallel means in the same direction as.

Thank you that is the answer I'm supposed to get to but is the -2 perpendicular to the y not parallel. If you could explain steps I'd be really grateful.
