Thank you so much! I was getting errors for LinReg and wondered what it was until I realized that my L1 was missing haha

Thank you very much professor!! This helped out tremendously and I’m not vomiting anymore 😁

Once I go to Lreg there is no options and no L1 L2 data even though I have entered it into stat like the first step. This is where I keep getting stuck. TI83

Another way you can turn on diagnostic is my clicking on mode on pressing the up arrow until you see the diagnostic option

How do you calculate X when you have a Y value? All the tutorials only explain how to calculate Y from X. Obviously you can do it by rearranging y=ax+b to x=(y-b)/a and doing manual calculations. But isn't there a way to just plug in the y values in the calculator?

How do you graph the LinReg of L1 with L3?
