Determining Slope from Graphs

The video tutorial introduces the concept of slope, describing it as the steepness of a line. It explains the four types of slope: positive, negative, zero, and undefined. The tutorial also covers the notation of slope using the letter 'm', derived from the French word 'montieux'. It provides a step-by-step guide on calculating slope from graphs by identifying two points, determining the rise or fall, and the run. Several examples are given to illustrate the calculation of different types of slopes.
