How to use the calculator to find and graph residuals:

Important things to edit:

(for step #4) cross out the first part and only follow directions after you see the word OR -> (under L3, use 2nd STAT #7 instead).

(for step #5) take note that the residual graph does not use L1 and L2.  you must change L2 to L3 (or wherever you entered the residual).
