So you want to detrend your data? The detrend function has existed since before release R2006a.

Take a look at the examples on the documentation page for the function to see if any of them look like what you're trying to do. If they do, adapt them to suit your needs. If they don't, explain in more detail exactly what you mean by "extract the linear x and y data".
doc detrend
