Graphing Lines in Point-Slope Form

The video tutorial explains how to graph lines using point-slope form by identifying a point and a slope. It introduces the formula y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line. The tutorial provides an example of graphing an equation and applies the concept to a real-world problem involving costs at a fair. The video concludes by summarizing the process of graphing lines in point-slope form.
