The video tutorial explains the distance formula in the XY plane. It begins by introducing the concept of coordinates and how to draw perpendiculars from points to the axes. The tutorial then demonstrates how to calculate the lengths of line segments using the differences in coordinates. By applying the Pythagoras Theorem, the video derives the distance formula. The tutorial concludes with a call to action for viewers to like, comment, and subscribe.
