Understanding Slopes of Horizontal and Vertical Lines

The video tutorial explains how to determine the slope of horizontal and vertical lines. It begins by defining slope as the ratio of vertical change to horizontal change. The tutorial demonstrates calculating the slope of a horizontal line using two points and the slope formula, showing that the slope is zero. It then applies the same method to a vertical line, illustrating that the slope is undefined due to division by zero. The video concludes by reinforcing that horizontal lines have a slope of zero, while vertical lines have an undefined slope.
