Answer:

Step-by-step explanation:
First find the midpoint of the segment from (2, -6) to (-4, -16)
((2 - 4)/2, (-6 - 16)/2)
(-2/2, -22/2)
(-1, -11) is the midpoint and is the center of the circle
Now find the distance between the 2 given points and divide by 2 to get the radius of the circle
d = 
= 
= 
= 
r =
/2
= 136/4 = 34
Equation of circle with center at (-1, -11) and radius =
is

Answer: it is 10 over 100
Step-by-step explanation:
-9x-5y=12
C) (2, -6) -18+30=12
