Question 971034
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 {{{(x-2)^2 + (y-3)^2 = 100}}}.
All points satisfy the equation except C. (-2,6).
{{{(-2-2)^2 + (6-3)^2 = 25}}}
Answer: C. (-2,6)
