  • Algebra 1 -

    the rate of change is the slope of the line. That is, if x changes by 1, how much does y change?

    In the slope-intercept form, the rate of change (slope) is m, in

    y = mx+b

    The point-slope form of a line is

    y-k = m(x-h)

    where the line passes through (h,k) with slope m. It's just another way of writing

    (y-k)/(x-h) = m

    That is, the slope (m) is the ratio of the change in y over the change in x.

    I'm sure all of this is explained in your text, with examples.

    So, with all this info, you should have a handle on solving the problems you posted.

    If you are given a slope and an intercept, choose the slope-intercept form.

    If you are given a point and a slope, use the point-slope form.

    If you are given two points, figure the slope, then use one of the points and the point-slope form.

    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 …
