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)

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 EXE' /> key

after plotting;

for y-intercept two methods are available:

1- hit Shift' /> / F5' /> (G-SLV)/ F4' /> (Y-ICPT)

2- hit Shift' /> / F5' /> (G-SLV)/ F6' /> (>)/ F1' /> (Y.CAL)

and input 0 for X-Value

and for x-intercept:

hit Shift' /> / F5' /> (G-SLV)/ F6' /> (>)/ F2' /> (X.CAL)

and input 0 for Y-Value

Another place where casio excels and TI fails...
