    Explanation of slope !!!

    1) Vertical line = infinity (or no slope) "I say" "Slope is always defined as rise/run. In a vertical line, you rise infinitely, but you have no run, so you have some number as your rise/0. Anything divided by 0 is undefined, so the slope of a vertical line is undefined." Response....saying I am wrong No slope is not t
