The point (0,5) lies on a circle that is centered at the
origin. Does (-3,-4) also lie on the circle?
1. Identify the radius from the graph.
r= Yunits
2. Determine the distance from the center to
(-3, 4) using the distance formula
distance = y units
3. Compare the radius to the distance. Does the
point (-3,-4) also lie on the circle?
