The video tutorial explains how to find the equation of a line given two points. It covers the formula y = mx + b, where m is the slope and b is the y-intercept. The tutorial guides through calculating the slope using the formula m = (y2 - y1) / (x2 - x1) and finding the y-intercept by substituting a point into the equation. The process is demonstrated step-by-step, emphasizing the importance of correctly identifying and labeling points to avoid errors.
