Which of the following points is on a circle if its center is (-13,-12) and a point on the circumference is (-17, -12)?

use the distance formula to find the distance between those 2 points, that is the radius. Call it R

The formula for the circle witll be

\((x+13)^2+(y+12)^2=R^2\)

Plug the points in and see which one makes the formula true.
