Finding Slope given the Line

The video tutorial explains how to find the slope of a line on a coordinate plane. It begins with a question about selecting coordinates, emphasizing the use of solid numbers. The tutorial then demonstrates using the slope formula, y2 - y1 over x2 - x1, with chosen coordinates (15, 2) and (0, 1) to calculate the slope as 1/15.
