Vector to matrix (pretty silly question)

Does it matter how you change vectors into a matrix?

Let's say you were given
(2,1,1), (3,5,9),(5,4,3)

and you had to figure out the inverse or L.I
would it matter if you made the matrix into:
(2,1,1)
(3,5,9)
(5,4,3)

rather than:
(2,3,5)
(1,5,4)
(1,9,3)

So for one I turned the vectors into the columns of the matrix and the other into rows. In my example book it does it in different ways and keeps interchanging
