    numerical value

    Slope = rise/run. But I need a value like Slope =7/6 a numerical value. Maybe to identify the points from the coordinate grid to find the slope usign the Pytagorian formula.

    Eg A(7,9) B(4,6). AB = ...
    or m = y2 - y 1/ x2-x1
    Please help. Any ideas...

    > m = y2 - y 1/ x2-x1
    START being more careful: that needs brackets: m = (y2-y1) / (x2-x1)

    Using your example, slope = (6 - 9) / (4 - 7) = -3 / -3 = 1

    Using A(2,5) and B(6,8): (8 - 5) / (6 - 2) = 3 / 4

    It's that simple: don't complicate it
