So one minus.5, so this residual here, this residual is equal to one minus 0.5, which is equal to 0.5, and it's a positive 0.5. And if the actual point is above the model, you are going to have a positive residual. Now the residual over here, you also have the actual point being higher than the model. So this is also going to be a positive residual. And once again, when x is equal to three, the actual y is six. The predicted y is 2.5 times three, which is 7.5 minus two, which is 5.5. So you have six minus 5.5.
