The video tutorial explains how to derive the equation of a linear function from a graph. It covers two methods: a detailed step-by-step approach using formulas to find the slope and y-intercept, and a quicker graphical method. The tutorial emphasizes understanding the slope-intercept form and provides practical examples to illustrate the concepts.

Which formula is used to calculate the slope of a line?

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

m = (Y1 + Y2) / (X1 + X2)

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