Understanding Slope of a Line

The video tutorial explains the concept of slope in mathematics, using the slope formula. It begins with an introduction to the slope formula, where 'm' represents the slope, and provides a mnemonic to remember it. The tutorial then walks through an example, demonstrating how to label ordered pairs and plug them into the formula to calculate the slope. The process involves subtracting y-coordinates and x-coordinates, simplifying the result, and reducing fractions. Finally, the video offers tips on simplifying the process and emphasizes the importance of careful sign management during calculations.
