Learn to graph a circle when given two points o the diameter

The video tutorial explains how to find the equation of a circle given the endpoints of its diameter. It begins with plotting the points on a graph, then uses the midpoint formula to find the circle's center. The distance formula is applied to determine the radius. Finally, the circle's equation is completed using these calculated values.
