Using slope triangle to find the slope of a graph

The video tutorial explains how to find the slope of a line on a graph. It begins by defining slope as the change in Y values over the change in X values. The instructor introduces the concept of a slope triangle, which helps visualize the change between two points on a graph. By selecting two points, such as (-2, 0) and (0, 4), the instructor demonstrates how to create a right triangle and calculate the slope by determining the rise and run. The slope is calculated as 4/2, which simplifies to 2. The lesson concludes with a brief Q&A session.
