Basic Algebra: Finding Slope
Hello, hello.

I need some quick help with finding slope when they give you:

2x + 3y - 9 = 0

From there, how do I find slope?

you have to put the equation in the form $y=mx+n$
And $m$ is the slope.

Oh, gotcha! Thanks! Umm, mind if you be my buddy for a bit? I'm doing about 30 problems here, which are, of course, seperated in different types of problems. :D

Just wondering if you'd answer any questions I may have, because I'll have more than one. :p

EDIT - So it goes like this?

2x + 3y - 9 = 0

Add 9 to both sides...

2x + 3y = 9

Subtract 2x from both sides...

3y = -2x + 9

Then divide by 3 ?

y = (-2/3)x + 3 ?

Yes!
And the slope is $\displaystyle m=-\frac{2}{3}$
