How do you figure out the slope without drawing the graph? I kinda forgot. I have a chart with data, and I need to know the slope

please help

thank you

    help please?!

    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)

    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.

    This one really threw me off... find the slope of the line containing the points (x, 2x) and (x + h, 2(x +h)) You have to first find the slope, which is change in y over change in x: {[2(x-h)]-2x}/[(x+h)-x] (2x-2h-2x)/(x+h-x) -2h/h …
