    help please?!

  • math -

    slope is the change in y divided by the change in x

    Pick two data points

    (x1,y1) (x2, y2)

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

  • math -

    yes, that's what i meant. i meant to pick two points, not just one.

  • math -

    ysub2-ysub1
    ------------= slope
    xsub2-xsub1

    the points are (x,y), obviously. just fill it in.
