So you have six minus 5.5. So here I'll write residual is equal to six minus 5.5, which is equal to 0.5. So once again, you have a positive residual. Now for this point that sits right on the model, the actual is the predicted. When x is two, the actual is three, and what was predicted by the model is three. So the residual here is equal to the actual is three and the predicted is three, so it's equal to zero. And then last but not least, you have this data point where the residual is going to be the actual when x is equal to two is two minus the predicted.
