Helo everybody!
I would like some help...
I need to do a report on how prime numbers are used in email encryption...
Now this is the problem, I have looked about on the net and the library and have found nothing helpful.
If you guys know any websites or anything that could help me is grately appreciated.

Uh, no.

Standard form is y=mx+b, with m being the slope and b being the y-intercept.

In your example, y=4x+3 is standard form.

The process is something like how you solve an equation, but in
reverse. In solving an equation, you want to transform it into an
equivalent equation of the form "y = ?", which you do by taking a
series of steps that gradually get y by itself. What you want to do
here is to transform it into an equation of the form "?x + ?y + ? =
0", which means that x and y and the constant are all on the same
side, rather than one variable being alone on the right.

Let's take an example. Say we're given

y = (1/2)x - 2/5

We want x, y, and the constant on the same side, so let's just
subtract y from both sides and we get

0 = (1/2)x - y - 2/5

Everything looks right except that the zero is on the left; I've
already arranged for the terms on the right to be in the right order.
So we can just write

(1/2)x - y - 2/5 = 0

Now, there's one thing we can do to make this look nicer; we'd like A,
B, and C to be whole numbers rather than fractions, since fractions
complicate things. To eliminate fractions, we can multiply the whole
equation by the LCD, which is 10. Do that, and we get

(10/2)x - 10y - 20/5 = 0

5x - 10y - 4 = 0

And we're done!

Actually, Ax+By=C is standard form.
