So first thing I did was parametrize the line. I used $gamma(t)=(5,t,2+frac23t)$ For $tin [0,3]$
I then have $F(gamma(t))=(2+frac23t,-t,5)$
and $dotgamma(t)=(0,1,frac23)$
Then $int_C Fdx=int_0^3 langle F,Trangle=int_0^3 -t+frac103dt=-frac23$
I'm pretty sure my parametrization is incorrect as I dont think I should get this negative.

Your calculations are correct; except the last step of the integration, which is $$int_0^3left(frac103-tright)mathrm dt=frac112.$$
