Hey all, I'm stuck in having to do a problem on my homework. It goes like this...

F(x,y) = <-y, x>, r(t) is the graph y = x^2 from (0,0) to (3,9).

My best guess right now is having the bounds of said integral from 0 to 3. Besides that, I do not know what to do to start setting this up. Any help to get me started on it? I'm trying to evaluate the line integral, nothing in my notes has a problem looking like this.
