Evaluate the line integral, where C is the given curve.

$\displaystyle \int_C xy~dx + (x-y)~dy$ C consists of line segments from (0,0) to (2,0) and from (2,0) to (3,2)

can someone help me set this up properly? I thought I was doing it right, but seem to be getting incorrect answers.

Also, latex doesn't seem to like this format or something, but the actual integral is: the integral over the curve of xy dx + (x-y) dy
