(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

do the lines (x,y,z) = (5+2t, 3+2t,1-t) and (x,y,z) = (13-3r, 13-4r, 4-2r) intersect? If so, at what point? If not, how do we know?

2. Relevant equations

3. The attempt at a solution

I just do not know where to begin...

I mean what do you do with the variables t and r.

Do those values constanly change?

If you want to direct me to some useful information to help me understand this concept.. feel free to do so
