it is called best fit because it minimizes the sum of square of the distances of points from line. That is to say, if you add up the squares of the distance of the different data points from the line, it will have the smallest value and it is in our interest to have the distance of the point from the line be as small as possible given by ziar khan

When Ax plus By equals C passes through the origin will C equal 0 on the graph?
Yes Ax + By = C As the line passes through the origin then x = 0 when y = 0. Substituting gives, 0 + 0 = C therefore C = 0.

If y = 4x then there is no y intercept because the line passes through the origin.
