8th Grade Math

posted by .

Can someone please help me with the following problems? I do not have the formula for finding the slope of a line. These are not homework they are for a portfolio.

Find the slope of each of the following lines.

1. y=-5-17

2. 10 + y = x

3. y = -2x - 5

4. 4x + y = 0

5. 3x - 4y = 16

6. -2y - 16 = x

7. y = -11x - 3

8. y = 13x - 14

9. 2y = 2x = 18

10. 6x = 5y = 10

Thank you very much if you are able to help.

    Why would you include these problems in your portfolio if you can't solve them?

  • 8th Grade Math -

    I don't know. We were just told to solve them. We were not given a formula.

  • 8th Grade Math -

    y = mx+b
    m=slope

    Just get it in that form to find what m is.

  • 8th Grade Math -

    y=mx=b
    m=slop

    The formula is actually simple to remeber if you've learned it.
    y=mx+b
    m=slope
    b=constant(y-intercept)

    or y=a+bx
    it's essentially the same thing, just in a differnt, more current form.
    in this one,
    a=constant
    b=slope

    oh, slope is also your rise/run which is y/x

  • 8th Grade Math -

    y=a+bx
    basic knowladge just put diffrently in more simpler form would be
    in what a= constant
    in what b=slope :)
