Finding the Slope with Points

The video tutorial explains how to find the slope using points instead of graphs or tables. It begins with a brief introduction to the concept of slope and the formula y2 - y1 over x2 - x1. The instructor then explains the components of a point, consisting of x and y coordinates, and how to label them as x1, y1, x2, and y2. The video demonstrates how to apply the formula by plugging in the values from two points and performing the necessary calculations to find the slope. The tutorial concludes with a final calculation, emphasizing the importance of correctly handling negative numbers in the formula.
