How to find line of best fit.

Thank you @Philq02! That would be very helpful if I wanted to find the best fit of a linear model. Sadly, I want the best fit in general; and it looks like the best fit contains a division (e.g. a/X + b * X where a * b would need to be estimated). Hey - this gives me an idea - maybe I can use OLS and provide 1/X as one of the predictors.
