I'm trying to figure out how to enter the following problem on my TI-84+SE:
"Graph the equation -2x-y=1 using slope-intercept form."
What keystrokes do I need to execute to do this? Thanks in advance for your help!
I don't know how to put y into equations either.
The problems I'm working on are not for a class, they're from books I'm studying to get ready for the CLEP test. I'm just trying to apply the calculator to the problems.

1. transcribe the equation to:
2. go to the
3. write at \Y1= -2x - 1. Take care that you use theto type the sign in front of 2x
4. open the:
I suggest that you use the following settings:
xmin = -5
xmax = 4
xscl = 1
ymin = -5
ymax = 4
yscl = 1
xres = 1
5. press theto draw the graph.
Thanks, Earboth!
Does that mean that everything is solved as y?
Let's say I have something like 3x * 35y * 22z.
Do I need to solve z as y, x as y and y as y?
If so, can you tell me how that would be done with keystrokes? Maybe there's a better example you can give me.
I don't know how to make signs for square root, etc. on this keyboard. Any advice?
Thanks again

Hello,
honestly I don't understand what you mean.
1. You can only solve an equation. What you have given is a term in 3 veriables which you can't "solve". Please say what you want to do with this term.
2. As for the mathematical symbols which are used at this forum have a look here: http://www.mathhelpforum.com/math-help/735-post1.html
