Lesson Summary:

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.

Lesson Description:

Several examples of graphing lines using their slopes and y-intercepts, and determining whether they are parallel or perpendicular.

    A good review of how to graph lines as well as a great explanation of how to determine whether lines are parallel or perpendicular. Great for learning about slopes of lines as well as for a review of parallel / perpendicular lines, or simply graphing lines.
