Graphing Lines Using Slope Intercept Form

In this video, Paul explains the slope-intercept form of a line, represented as y = mx + b, where m is the slope and b is the y-intercept. He demonstrates how to identify these components in an equation and use them to graph lines. Two examples are provided: one with a positive slope and another with a negative slope. The video concludes with a prompt to subscribe for more math tutorials.

What does 'M' represent in the slope-intercept form?
