the general circle equation is ... (x - h)^2 + (y - k)^2 = r^2
(h,k) is the center of the circle , r is the radius
the equations of the two points should NOT be equal
... and they should have the correct format
PLEASE HELP ASAP!!
Point (4, 2) belongs to the circle with the center at (-1, 1). Which statement verifies that the point (-5, -3) is NOT on the circle?
A. (4 + 1)2 + (2 - 1)2 ≠ (-5 + 1)2 + (-3 - 1)2
B. (4 - 1)2 + (2 + 1)2 ≠ (-5 - 1)2 + (-3 + 1)2
C. (-1 + 1)2 + (4 + 1)2 ≠ (-1 + 1)2 + (-5 - 3)2
D. (-1 - 1)2 + (4 - 1)2 ≠ (-1 - 1)2 + (-5 + 3)2
