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
In three sentences or less, describe how we evaluate a function. A brief definition of a straight line graph is a linear function of the form y = mx + c, where c and m are constants.
