First, use the mid point formula to find the center of the circle.
Midpoint formula:
Since the points are located on a straight line, our next task, finding the radius, is a whole lot easier.
The radius is 4.
Now, using the formula
Here is the graph of your circle:
graph{(x - 2)^2 + (y - 3)^2 = 16 [-10, 10, -5, 5]}
Hopefully this helps!
