# Enter your points. On the TI83 and TI84, all editions, go to "STAT" then scroll down to "Edit" and press enter. You will be taken to the list editor. If there are already entries in L1 or L2, move your cursor over the text "L1" or "L2" and press clear, then press enter to delete all of the data. In L1, enter all of your x-coordinates in order pressing enter after each entry. In L2, enter all of your y-coordinates that correspond to the adjacent x-coordinates. Make sure they all match up so when you read from left to right, the ordered pairs are the same as your data. | # Enter your points.
