How to find the slope between two points

The video tutorial explains how to find the slope between two points. It begins by defining slope as 'rise over run' and introduces the concept of change in elevation and horizontal distance. The tutorial then explains the use of delta notation to represent changes in coordinates. It guides viewers on labeling points with subscripts to differentiate them and demonstrates the calculation of slope using an example. Finally, it discusses interpreting slope values and converting them into fractional form for graphing purposes.
