Compute Line Integral: (x/y) from (2,4) to (10,100)

[balrog1212]

The question is compute the integral over c of (x/y) where c is the line segment from (2,4) to (5, 25) followed by the parabolic arc from (5, 25) to (10, 100)

I tried setting this up in terms of x and then y using the line integral formula but I am got a negative answer which i know can't be right. Can anyone help me set this up?

What do you have for the function, it's derivative, and the integral?
