How to solve a system of equations of two perpendicular lines by graphing

The video tutorial covers the identification and graphing of perpendicular lines in a system of equations. It begins by discussing the concepts of parallel and perpendicular lines, assuming prior knowledge. The instructor explains how to identify perpendicular lines by examining slopes, noting that they are reciprocals and have opposite signs. The tutorial then demonstrates graphing these lines to verify that they intersect at a single point, confirming a consistent and independent solution.
