So if the, let me write it over here. If the squared error of the line is small, is small, it tells us that the line is a good fit. Line is a good, it tells us it's a good fit. Now, what would happen over here? Well, if this number is really small, this is going to be a very small fraction over here. One minus a very small fraction is going to be a pretty large, it's going to be a number close to one. So then, so then we're going to have our r squared will be close, close to one, which tells us that a lot of the variation in y is described by the variation in x, which makes sense because the line is a good fit.
