The video tutorial explains how to identify and calculate the slope of a line using graphs. It covers the concept of linear relationships, the definition of slope as a constant rate of change, and how to calculate slope using the rise over run method. Different types of slopes, such as positive, negative, zero, and undefined, are discussed. The video also explores the concept of proportionality in linear equations and introduces the constant of proportionality.
