We perform an experiment and obtain N data points (X1,Y10), (x2,y20), (XN, YNO). Here the subscript "o" on the Y values shows it is an experimental point. Now we're going to try to approximate those points with the line yir-mxi+c. We want to find the values of m and b that minimize the total error of the Sum of the Squares (SS). Doing the necessary substitutions and algebra we find that we can express the Sum of the Squares algebraically as SS=[yio²-2c[yio -2m[xiyio +2mc{xi+Nc²+m²[x² Explain and justify (NOT do mathematically) how can we now find the slope m in terms of xi and yio only?
