If (9, 1) and (1, 9) are the endpoints of a diameter of a circle, what is the equation of the circle? A)(x − 5)2 + (y + 5)2 = 64 B)(x − 5)2 + (y − 3)2 = 72 C)(x + 5)2 + (y +3)2 = 32 D)(x − 5)2 + (y − 5)2 = 32

6/20

step-by-step explanation:

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)

step-by-step explanation:

infinity is the answer

noncoplanar points are points that do not lie on the same line.
