Finding where a slope becomes linear

I recently took a class teaching Matlab and I'm trying to use it at my internship to find where our plotted data, using a vector of x and y data values, starts to become linear. I am trying to use a polyfit and then find the slope using the maximum slope and find the y value of where that begins. Can someone help me?

What is a vector of x and y data? What exactly is a linear slope? Are you looking for a zero curvature? How do you use the maximum slope to find the value where what begins?

I'm not sure about the question. Perhaps you are looking for this:
curvature = diff(diff(x));
find(curvature < 1e-6)
