I have a TI-83 Plus calculator and was wanting to plot some data from my homework, but when I want to insert the x and y on my calculator, I only have an X column and no Y column. How can I add that column in order for me to plot my data?
I'm looking at my calculator but I really don't know under what button your looking under. Maybe If you told me what are you looking under and what your plotting exactly maybe I could help you out.
What I am looking at is press the 2nd key and then graph..I would like to plot (-1,-4) to make sure that I plotted it right.
