This is going to be equal to 1 3rd plus 155 over three, which is equal to 156 over three, which comes out nicely to 52. So the predicted on our line is 52, and so here, so this person is 155, we can plot them right over here, 155. They're coming in slightly below the line. So they're coming in slightly below the line right there, and that distance, which is, and we can see that they are below the line, so that distance is going to be, or in this case, the residual is going to be negative, so this is going to be negative one. And so if we were to zoom in right over here, you can't see it that well, but let me draw, so if we zoom in, let's say we were to zoom in the line, and it looks like this, and our data point is right, our data point is right over here. We know we're below the line, and this is going to be a negative residual, and the magnitude of that residual is how far we are below the line. And in this case, it is negative one.
