If we assume that the best line representing the coordinate pairs of points resulting from an experiment is: Y=mX+b, and the deviations of the experimental points with respect to that line are: Y_i=Y_i-(mX_i+b), then the least squares principle guarantees that:

(2) ) is minimum. b) is m minimum is minimum ) 2 is minimum 2-0 Choose the correct subsection and justify your answer.
