The graph of a circle has its center at (2,3) with a radius of 10 units. Which point does not lie on the circle?
A. (-4,-5)
B. (8,11)
C. (-2,6)
D. (-4,11)
Solution:
The equation of the circle is %28x-2%29%5E2+%2B+%28y-3%29%5E2+=+100.
All points satisfy the equation except C. (-2,6).
%28-2-2%29%5E2+%2B+%286-3%29%5E2+=+25
Answer: C. (-2,6)
