I am supposed to find the line integral over C of (x+y)ds where C is the line segment from (0,1,1) to (3,2,2)?

So far I have 3ti + (1+t)j + (1+t)k as the parameterisation of C, and when I make an integral from that, I get 3(sqrt(11)). But I am uncertain of this answer, so if anyone could help confirm that (or even just the parameterisation), that would be very helpful. Thank you!

    how do you start this problem: integral of xe^(-2x) There are two ways: 1) Integration by parts. 2) Differentiation w.r.t. a suitably chosen parameter. Lets do 1) first. This is the "standard method", but it is often more tedious
