Write The Equation of a Line Given the Slope and Intercept

The video tutorial explains how to write the equation of a line using the slope-intercept form, focusing on the roles of the slope (M) and Y intercept (B). It provides examples of writing equations with given slope and Y intercept, understanding Y intercept as a coordinate point, and explains horizontal and vertical lines with zero and undefined slopes, respectively. The tutorial concludes with a preview of more complex problems involving different forms of line equations.
