Linear … NettetAs already mentioned by belisarius, the canonical method for finding the equation of the least-squares line constrained to pass through the origin in Mathematica would be either of. Fit[data, {x}, x] which produces the explicit linear function, or. FindFit[data, m x, m, x] which produces just the slope of the best-fit line as a replacement rule.
