Parallel and Perpendicular Lines: Understand and Calculate Equations

The video tutorial explains the concepts of parallel and perpendicular lines. It covers the properties of parallel lines, such as having the same gradient but different y-intercepts, and demonstrates how to calculate their equations. The tutorial also introduces perpendicular lines, explaining that their gradients are negative reciprocals of each other, and provides examples of solving problems involving these lines.
