Question

Point P (-1, 2) is the center of a circle. The radius of the circle is 3 units. Which point lies on the circle? PLEASE HELP!

Answer 1

(2,2), (-1,5), (-3,2), (-1,-1)

Explanation:

The radius is the distance from the center of the circle to the outside. So, adding or subtracting 3 from the x-value of the center point will give you a point that lies on the circle. Doing the same to a y-value will as well. However, never add or subtract from both.
