Question

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

Answer 1

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
