    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.

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

    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}
