Hey,

Not sure if this is the right section to post this but ...

I have a graph for which im supposed to fit two linear least squares line and minimize the combined residuals (the lines intersect)... I would really appreciate some info about how to do this or what this type of data analysis is called so i can google the step-by-step method.

Thanks!

You haven't clearly described what you are trying to do. My guess is that you should search on the phrase "piecewise linear regression".
