Limits and Derivatives help

[FalconPUNCH!]

I tried this several times but couldn't get it right. I do not want answers to this. I just need help on how to set it up.

The point P(1,1/2) lies on the curve y = x/(1+x).
[A] If Q is the point (x, x/(1+x)), find the slope of the secant line PQ.

I just don't know how to set the equation up. Please help as soon as possible. Thank you

Slope of a line joining two points (x_1, y_1) and (x_2, y_2) is:

m = (y_2 - y_1)/(x_2 - x_1)
