Find an equation of the circle that satisfies the stated conditions. (Give your answer in standard notation.)
Endpoints of a diameter A(−8, 5) and B(6, 9)
-----------
Find the center, (x,y)::
x = (-8+6)/2 = -1
y = (5+9)/2 = 7
(x,y) = (-1,7)
-------
Find the radius, r ::
Find the distance from (6,9) to (-1,7)
r = sqrt[(9-7)^2+(6--1)^2] = sqrt[4+49] = sqrt(53)
--------
Equation:
(x+1)^2 + (y-7)^2 = 53
