Mean response estimates the y value assuming that it lies on the line (the mean of the points).

Individual response estimates the y value of a individual point which if you recall is on average on the line - but is distributed around it with variance \(\sigma^2\).

Hence it has the same mean but a variance that is \(\sigma^2\) more.
