On my TI 84 Plus CE, I have $Y_1$ and $Y_2$ filled with equations, both under Plot 1. When I select Plot 1 and press enter to select it to graph, the plot doesn't show up under graph. Instead, I see a scatter plot based off of my data in $L_1$ and $L_2$. I go to 2ndstat plot and turn off Plot 1, but then Plot 1 under y= is also deselected.
What's going on, and how can I fix it?
