How to make a line of best fit on desmos.
Desmos employs various strategies to mitigate these difficulties. The calculator makes several initial guesses for each parameter, refines them many times, and returns the best one. The calculator also uses some heuristics to help choose among several solutions when it encounters a best-fit that is not unique.
