Nothing to be ashamed of. Everyone has to start somewhere.
Why would you expect linear algebra in a thread asking for assistance with linear equations?
Ok silasraven I don't understand what you mean by packets etc..... but you can go back. It is the fastest way and you have to. You are floundering. Do what Carne Seca suggested and get to a tutor so they can help you. You can also do this online today.
I'd start here and quickly go through this to make sure I understood each concept listed:

http://www.waybuilder.net/free-ed/Math/algebraMix/obsolete/SOS01.asp
and here's where these are linked off of:

You can supplement your information. Oh yes and as for shame, I failed Algebra 1 twice and I had to start again at the beginning. Once I got back to basic math and I understood and took everything step by step I got it and I said the same thing you are saying now, "I am just not good at math". When the truth is math (at this level), is failed because you go past an area of misunderstanding. Once you've done that you are sunk.

I`ll give this a go. I was having trouble with maths a while back and I know what its like.
You will always have a Y axis and an X axis. Y is the dependant variable, X is the independant variable. That means you control the value of X (from minus infinity to plus infinity) and sketch Y accordingly. Unless you have the variable X in a limit, say from +5 to -5, your graph will be an infinate sketch. If it is not limited then the teacher will only expect a basic sketch.
So for example you are given an equation of the form Y - 2 = X
Remember, you want Y expressed in terms of X, as it depends on X. When sketching graphs, X axis holds the independant, Y holds dependant. For example a voltage depending on time would have voltage on Y and time on X.
Rewrite in the form Y = X + 2.
This is your Y axis. For every increase in X, Y increases by a constant C.
So you have this in the form: Y = m.X + C
Where m is the gradient (1 in your case, X.1=X) and C is the +2 constant on your graph. ANY function in the form Y=mX + C will create a straight line graph. Fact.
When starting to sketch a graph, there is a few key points to consider. One will be where the graph crosses the X axis, and where it crosses the Y axis.
Visualise this, let X=0. This means the graph is crossing the Y axis at that point. Let Y=0, this means the graph is crossing the X axis at that point.
You can solve the equation for this, Y=X+2. So let Y=0. We have 0=X+2 so X= -2 is where the graph crosses the X axis. Let X=0. You now have Y=0+2, Y=2. Graph crosses Y at 2.
Then write a litte table down with values for X. Range it from -3 to +3 with 0 in between. For every value of X, tabulate a value for Y using the equation next to it.
Now you know where the graph crosses the axes, and also have 3 points to plot on the graph. You don`t even have to plot those points as the graph is a straight line and will increase linearly from where it crosses the axes. Just put ruler and sketch
I gave it a go dude, for you to properly understand this u gotta visualise it. Plot your own points!
If you want a good idea of this thing, try plotting Y=X.X (as in X squared). It will be a parabola with no negative Y values as minus times minus always equals plus on the Y

gods telling me not to pick fights with you, but i must ask, at the least, why do you assume??? your not doing anything but helping me figure out how to put these problems into the right place. i still have to graph them. not doing my work for me just helping me find the answer, never asked you to use the same numbers i gave you.

if god is so benevolent, why did he make it so easy for some people to do linear equations and so difficult for you?
did god make a mistake? is he out to get you? is he rooting against you?

Alright stop being mean. Math classes suck. He's just asking for a little guidance. Gosh.

god doesnt make a mistake, he made me to not understand math as easy as everyone else so it takes me longer for a reason. if i was as good at everything as everyone else i wouldnt be in the places he needs me to be at the times he needs me to be.
as for rooting(looks into closet) i think not with the forestry he has given me.

lol, have fun turning over your life to an imaginary sky daddy.

hmm before i turned it over to my sky dad father as you so elegantly put it i wasnt passing much of anything, new report. my heavenly father saw it befiting to give me COLLEGE!!!!! passed my writing and my reading into classes 101 and math 91 so yep he's paved my way to get into school and better my life as we speak.(or type) ive got classes soon enough so i can boost my school to get into math 101 .y life is better with god then without. hmm i offten thought of my life as an aithest but then i would be depressed and lifeless kind like my uncleOFUCK i thought i saw a cat sorry.

What are you taking ,cuz college is a lot harder the the entrance exams FYI

math 91 is what i got in, like i stated before i have a class starting in june 2 so i'll be hitting book hard and fast to make better scores, and its a community college anyway. but i hope to boost math till i hit university

My only advice , NEVER use a caluator even if you have one next to you. You are going to need to know how to do arithmetic & trigonometry in your head.

so sky daddy only watches out for you once you start believing in him? and otherwise, he's mean spirited dick?
LOL.

Shhhhh... shhhh... it works when you belive in him, don`t you listen?

well if you reject him, he will protect you but thats only if your listening. seeing as how most who reject him arnt listening you wont get to hear the huge siren he gives you telling you to STOP!

Although I usually enjoy your trolling and bantering, I want to remind you that when you step into the territory of Christianity, it's not just Silas you're insulting. So pretty please choose a different tactic for trolling, love. And maybe this time i'll send you real pictures

I tend to put believers in the same category as people who think Gilligan's Island is real.
Which is not to say I dislike them.
To me the perfect Christian, and he would probably disagree if he were not dead, was Fred Rogers.
That's right. Mr. Rogers.
If all Christians were like Mr. Rogers, I would not have a problem at all.
However, I do have a problem, if upon meeting someone for the first time; the first question out of their mouth is "Are you a Christian." I have an uncle who does that.
I have a problem if a believer expects me to bow my head when they say grace before a meal. In fact, it's a tad obnoxious to presume everyone at the table is down with saying grace out loud in public.
And around here, and for the life of me I have not figured this out yet, but when people find out I am a strict vegetarian; it is the Christians who inevitably ask, "Don't you believe in God?"
Back on topic.
Silas, did you go to that link I sent you? I hope it helped.
