Question

Which point lies inside the circle with equation (x − 2)2 + (y + 3)2 = 4? a(0, −3) b (2, 0) c (2, −5) d(2, −4)

Answer 1

d. (2, -4)

Explanation:

The equation describes a circle centered at (2, -3) with a radius of 2.

Any points with an x-coordinate of 2 must have a y-coordinate in the interval -3±2 = (-1, -5) to be inside the circle. One such point is ...
