Understanding Vertical Lines and Their Properties

The video tutorial explains how to find the equation of a line that passes through the point (3,1) and is perpendicular to the x-axis. It begins by graphing the point on a coordinate plane and then discusses the concept of perpendicular lines, emphasizing that they intersect at a 90-degree angle. The tutorial concludes by deriving the equation of the line, which is vertical and passes through the x-coordinate of 3.
