What do you mean by linear equations? Your calc can do Y=f(x), X=f(y), and f(x,y) graphs. It just depends what mode you select.

You can find intercepts by pressing (while on the graph screen):

Hello fixerj and welcome to UCF! You should introduce yourself.
What do you mean by linear equations? Your calc can do Y=f(x), X=f(y), and f(x,y) graphs. It just depends what mode you select.
You can find intercepts by pressing (while on the graph screen):F5' /> (G-Solv)
F5' /> (Intersect)
The graph screen can be accessed by pressing MENU->5. Press the <- or -> buttons while selecting an equation to edit it. To change the type of equation (like from x= to y=), press f3.

for (3x-6y=12) how is this performed on my cal.fx-9860g2 graph function for Y won't do it.

sorry about the intro error please forgive,i have since used the introduction thread to do so.my question is to find the Y and X intercept
for (3x-6y=12) how is this performed on my cal.fx-9860g2 graph function for Y won't do it.
hi
you should convert your eqution to this form ( y=(3x-12) / 6 )
and then input that into Y1(Menu/Graph) and hit

after plotting;
for y-intercept two methods are available:
1- hit



2- hit




and input 0 for X-Value
and for x-intercept:
hit




and input 0 for Y-Value
