Write the equation of the circle containing the points J(-3, -3), K(1, -3), and L(1, 1). Show all work to receive credit.
-----------------------
If you look at the points, or plot them, you'll see that they from a right triangle.
In the case of 3 points that make a right triangle, the hypotenuse is the diameter.
---------------
d = distance from (-3,-3) to (1,1)


------------------
The center of the circle is the midpoint of the same 2 points. Find it by getting the averages of x and y:
x: (-3 + 1)/2 = -1
y is the same
The center is (-1,-1) and the radius is given above.
-->
--------------------------------
If the points don't make a right triangle, it's more tedious.
