How is it that if you have a set of data, x1,y1....xn,yn with a known linear relationship between x & y (y = mx + c), and the best straight line fit MUST go through xbar,ybar (xbar average of all x values, ybar is average of all y values).
It's because men want us all to look fit with some curves, little to they realize girls with curves are the sexiest of all!
