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 defining the slope-intercept form and calculating the slope using the formula M = (Y2 - Y1) / (X2 - X1). After finding the slope to be -1, the tutorial proceeds to determine the y-intercept by substituting one of the points into the equation. The final equation is simplified to Y = -X + 4. The tutorial concludes with a graphical verification of the equation, confirming the slope and y-intercept.

Which formula is used to calculate the slope between two points?

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

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

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

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