Could someone please help me prove, that the slope in a straight line is

m = (y1-y2)/(x1-x2)

using the pythagorean method? I get a feeling that it's really simple but I'm feeling stupid today.

Thanks!

It's been a long time since I've been in Geometry, so I don't really remember how to do proofs.

<img src = "http://www.illusionaryworld.com/chalk.gif">

a = y2-y1
b = x2-x1

m = rise/run (this step is lacking, i know)

m = a/b
m = (y2-y1)/(x2-x1)

a^2 + b^2 = c^2

Then why do you bother asking?

If your that desperate goto: http://www.bbc.co.uk/h2g2 and explore there.

Wait I need something to make this post complete, I know

Speaking of which, will there be a School forum thing again?

Baloki, your attitude in your response was very unnecessary. Does it say anywhere that this is <i>just</i> a Homework Forum? No. It is the Help Forum. If you can't help...just don't post. That's what I do.

EDIT: Why was this thread moved into Feedback? *moves*
