# Line of Best Fit Formula

A line of best fit is a straight line that is the best approximation of the given set of data. In simple term, it is a graphical representation

A more accurate way of finding the line of best fit is the least square method. If you draw a line of best fit, it is possible to determine the equation of the line of best fit. You will remember that the equation of a straight line is given by

$\large y=mx+c$
