Comparing Slopes of Linear Functions

The video tutorial explains how to compare two linear functions by calculating their slopes from graphs. It begins with an introduction to the concept of slope as 'rise over run' and demonstrates the calculation for two functions, one black and one red. The black function has a positive slope of 2, while the red function has a negative slope of -2. The tutorial emphasizes selecting clear coordinate points to determine the rise and run accurately.
