Finding Slope from Two Points

The video tutorial explains how to find the slope of a line when given two points. It begins with a brief review of the point notation on a graph and introduces the slope formula: (y1 - y2) / (x1 - x2). The instructor provides two examples, demonstrating the step-by-step calculation of the slope using different sets of points. The video concludes with an invitation to ask questions, like the video, and use a free worksheet for further practice.
