# Simple line integral problem I cant seem to get

I have to evaluate the line integral :
$\oint_{}^{} (2x + y)dx + xydy$ between (-1,2) and (2,5)

on the curve: $y = x + 3$

So, what I did was:
$\int_{-1}^{2} (3x+3)dx + \int_{2}^{5} (x^{2} + 3x)dx$

However, this is wrong and im not sure why!
Thanks alot!
