One time I was bored translated this formula to work on a TI-83 calculator
The original does work or course but it doesn't look right since the TI-83 isn't as precise as something like Desmos. You have to change the numbers around a bit to make it look right
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.
You can zoom on the TI-83/TI-84 by either using the zoom functions or by setting the desired viewport size
