The video tutorial explains how to write the equation of a line using the slope-intercept form. It covers the necessary components: slope and coordinates. The instructor demonstrates finding the X and Y coordinates using the unit circle and cosine function. The slope is calculated by taking the derivative of the function and evaluating it at a given point. Finally, the line equation is formed by combining the slope and coordinates.
