# I can't graph lines on my TI-84 Plus

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?

I'm still not sure what happened, but I deleted the values in $$Y_1$$ and $$Y_2$$ for the umpteenth time, and suddenly everything worked fine.
