Understanding Gradients and Slopes

This video tutorial explains how to calculate the gradient or slope of a straight line. It covers the concept of gradient as the rise over run, with examples demonstrating positive and negative gradients. The video includes two example problems, showing step-by-step calculations of the gradient between given points, emphasizing the relationship between the rise and run in determining the slope.
