The video tutorial explains how to determine the equation of a line using the formula y = mx + b, where m is the slope and b is the Y-intercept. It demonstrates finding the Y-intercept by identifying where the line crosses the Y-axis. The tutorial then explains how to calculate the slope using the rise over run method by selecting two points on the line. Finally, it combines the slope and Y-intercept to form the complete linear equation.
