What is slope and how do you measure it? Slope is a measure of how steep a line is. It can be calculated by using rise over run.
Rise is the vertical measure and run is the horizontal measure.
A positive slope indicates that the line is rising from left to right. A negative slope indicates that the line is falling from left to right. A zero slope indicates that the line is horizontal and a vertical line has an undefined slope.

I'm working through the whole Algebra 1 course. Here is a list of the videos in order I have completed so far.It should be a helpful review of the entire Algebra 1 course.
