Question

Which one of these points lies on the given circle?

Answer 1

Answer: C. $(2, \sqrt{5})$

Step-by-step explanation:

The x coordinate is 2, which is 2 units right of (0, 0)

- √5 is the y coordinate

- (√5) = - (2.23) = -2.23

The y coordinate is -2.23 or 2.23 down from (0, 0)

The rest of the ordered pairs are slightly off the edge of the circle.
