Determine two sets of parametric equations for the line passing through the points P(1,7,1) and Q(3,4,4)

I got one of them but I don't know how to get a second parametric equation.
first one: x=12s, y=7+3s, z=13s
second:???

why not use the other point?
x = 3  2x
y = 4 + 3s
z = 4  3s

I was thinking about that, ha~ but thought it would be wrong.
Thanks!
