Answer:

(0, - 1), (- 4, 3 ) and (0, 7 )

Explanation:

Substitute the coordinates of the points given into the left side of the equation and if equal to the right side then they lie on the circle

Given equation

x² + (y - 3)² = 16

(0, - 1)

0² + (- 1 - 3)² = (- 4)² = 16 ← lies on circle

(0, 1 )

0² + (1 - 3)² = (- 2)² = 4 ≠ 16 ← not on circle

(- 4, 3)

(- 4)² + (3 - 3)² = 16 + 0 = 16 ← lies on circle

(0, 7 )

0² + (7 - 3)² = 4² = 16 ← lies on circle
