I am a student at Stanford University.
*[youtube xWZKDkERWbU] In this video lecture, I explain how to calculate and understand the slope of a line. I use a table of values of x and y for several functions to show the change in y per unit change in x. A graphical explanation of slope follows. I discuss the differences between positive and negative slope, and at the end of the video, I show where you can find slope in the formula of a linear function.
