Reading carefully, he stated "There is an infinity of possible lines OF THAT SLOPE." He does not, I think, argue with the concept of fitting to the actual slope, but rather questions, as I did, how to make the agonizing decision of where (horizontally and vertically) I should place the slope in relationship to the plotted points. He should be severally chastised for saying "line" instead of "line segment."But let's hear from him before we raise our back hair.
