This lesson explores how to graph lines using their slopes and y-intercepts, and how to determine whether lines are parallel or perpendicular. The instructor walks through several examples, highlighting how the slopes of the lines determine whether they are parallel or perpendicular, and how the y-intercepts impact the line's position on the graph. The lesson concludes by demonstrating how to verify whether lines are perpendicular using the 90-degree angle of a piece of notebook paper.
