The video tutorial explains how to write the equation of a line using two points. It begins with an introduction to point-slope form and the importance of labeling points as X1, Y1, X2, and Y2. The instructor demonstrates how to calculate the slope using the formula M = (Y2 - Y1) / (X2 - X1). After finding the slope, the tutorial shows how to write the equation in point-slope form and then convert it to slope-intercept form. The final equation is presented as y = -4/3x + 2/3.
