The video tutorial introduces the slope-intercept form of linear equations, y = mx + b, explaining its components: the slope (m) and the y-intercept (b). It details how to identify these components on graphs and calculate the slope using graph points. The tutorial also covers the concept of negative slope and concludes with a discussion on different equation forms.
