Find the slope of each line below.

  1. An increasing line, passing through the origin, and the point (10, comma  6).

    Slope can be defined as the change in over the change in .

    Pick two whole-number points on the line.

    The coordinates for two points on the line are (10, 6) and
    (5, 3). Now count the change in and the change in .

  1. An increasing line, passing through the origin, and the point (5, comma 6).

    Pick two points on the line.

    The coordinates of two points are (5, 6) and (0, 0).
    Find the slope. See part (a) for help.
