Any help with this question is greatly appreciated. I apologize now for my lack of knowledge on this calc. I've only had it a month, I've figured most of the things out on my own, but this one has me stumped.

I am doing a scatterplot, that part I have down. I need to get the equation for the data after I have plotted it. I've tried using the STATL button on the menu, then FCN VIEW to get the equation. For some reason it is returning an incorrect equation. I know this because I've tried several out of my Algebra book and do not get the correct answer. When I do the STATL instead of following the data plotted it does a diagonal line accross the screen and this is the equation it returns.

Can anyone help?

Thank you,

Karen
