Math help

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.



a = y2-y1
b = x2-x1

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

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

if you remind me what the pythagorean method is again, i might be able to help you! Feels stupid. :shame:

a^2 + b^2 = c^2

I don't do peoples maths homework, I have enough of my own.

pithagorus is really easy

It's not my homework, but thanks for your help anyway. Not.

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

NOT

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

I dunno, ask in Feedback :p

Baloki, your attitude in your response was very unnecessary. Does it say anywhere that this is just 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*

SO WAS I RIGHT OR WHAT?

If I figure it out, I'll let ya know.
