So I am given this:(adsbygoogle = window.adsbygoogle || []).push({});

Iflhas parametric equations

x = 5-3t

y = -2+t

z = 1+9t

find parametic equations for the line through P(-6,4,-3) that is parallel tol.

So, my question is this: for the two lines to be parallel, they have to have the same direction vector right? In this case, <-3, 1, 9>. So if I were to find the parallel line tol, it would be:

x = -6-3s

y = 4+s

z = -3+9s

Thanks!!
