I'm not understanding the vector parts. Sorry about this, but unfortunately, I'm not an expert at these sorts of questions. Maybe you should ask someone else. @whpalmer4 are you good at these questions at all?

\[r(t) = (1t)<1,3,2> + t<2, 1, 3>\]You essentially treat it like distributing and collecting terms: \[r(t) = <1(1t),3(1t),2(1t)> + <2t,t,3t> = <1t+2t, 33tt,2+2t+3t> =\]\[= <1+t,34t,2+5t>\]
