It's the last equation j(x) that's wrong. What's plotted on the right is something like 0.2x+1.6

Your graphing calculator is more than capable of plotting linear functions just as well as desmos.

I wasn't following the image, I was following Desmos's official formula.

The equation works, but since you can't zoom in on TI-83 (or at least I'm not aware you can) you have to scale up the formula to make the symbol appear properly.

i don't mean to be condescending but the TI-83/84 literally has a button labeled ZOOM

Does it really? Man I felt so accomplished when I figured out how to make that formula work. Could've just zoomed in.

Regardless it was a good exercise to mess around with the formulas and see what happens, you're the real winner for having developed a better understanding!
