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


  • Calculus -

    why not use the other point?

    x = 3 - 2x
    y = 4 + 3s
    z = 4 - 3s

  • Calculus -

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