x=-2 does not have a slope does it?

  1. Damon

    sure it does, m = intinity
    graph it, straight up and down parallel to y axis crossing x axis at x = -2

  2. deedee

    So the slope would be all numbers?
    Or is it just undefined?
    I have to give exact numbers.

  3. Damon

    There is no exact number but oo. The slope of a vertical cliff is infinite.
