The video tutorial explains how to determine the equation of a line passing through two points, (3,1) and (5,-1), in slope-intercept form. It begins by introducing the slope-intercept form and the formula for calculating the slope using two points. The tutorial then demonstrates how to find the slope, which is -1, and how to determine the y-intercept by substituting one of the points into the equation. The final equation of the line is y = -x + 4. The video concludes with a graphical verification of the equation, confirming the slope and y-intercept using the given points.

What is the formula for calculating the slope (M) between two points?

M = (X1 - X2) / (Y1 - Y2)

M = (Y1 - Y2) / (X1 - X2)

M = (Y2 - Y1) / (X2 - X1)

M = (X2 - X1) / (Y2 - Y1)
