Answer:
Okay so i use this all the time for my school so it graphs thing like functions, coordonates it also has a way you can add a table if u need it, to basically use it enter the y in ur equation like y=8x+9 and then the next bar would be x like x=9x+10 things like that and to graph a function u only need one bar and such to graph it that way, i'll put down some examples for you to look at and if u have any specififc questions i can answer those as well, Oh also if u put up 2 equations and only see one line you have to click the zoom out button on the right side of ur screen until u see the line.
Step-by-step explanation:
In the first picture i circled the important parts of the calculator which is the zoom out button, and the colors of the lines, you can also switch the colors if u want to as well, In the second picture it shows how to find the x,y intercepts if thats what you have to do. Whenever the lines intercept on a graph then thats what ur x and y intercepts are. If you have any more questions pls ask and i can answer them!
