Understanding Slope and Phone Usage

Curtis Brown and Robert Adoot discuss the concept of slope in the second video of their Smart Space series. They explore daily phone usage data, representing it in a graph to understand slope. The video explains slope using metaphors like skiing and roads, and demonstrates how to calculate it using rise over run. A real-world example of a steep road illustrates the concept further. The video concludes with a graphical representation of slope and its equation, emphasizing the relationship between days and phone hours.
