Determining Line Intersection

The video tutorial explains how to determine if two lines intersect by examining their slopes. It covers the concepts of intersecting and nonintersecting lines, including parallel and perpendicular lines. The tutorial demonstrates how to calculate the slope of a line using the rise over run method and the slope formula with coordinate points. It concludes by showing how to determine if lines intersect by comparing their slopes.
