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=1-2s, y=7+3s, z=1-3s

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!
