calc 3- line integrals over a path

could anyone please check my work, i got a crazy answer.

evaluate the line integral over the indicated path.

the integral of (x+y+z)dL

where C is the line segment joining the origin to the point (-8,2,1/3)

i am new to this and really unsure of my answers..so i easily get freaked out by weird answers. i got:

(-17*sqrt(613))/(27)

anyone want to double check my work for me please? i'll feel more confident with all of my answers. this problem only took me a few steps so it should be quick
