Exploring Slopes of Parallel and Perpendicular Lines

This video tutorial covers the concept of slope in graphing lines, including how to calculate slope using the rise over run formula. It explains the properties of horizontal and vertical lines, and how to graph lines using the slope-intercept form. The video also discusses how to analyze slopes to determine if lines are parallel or perpendicular, and applies these concepts to solve practical problems.
