On a coordinate plane, a circle has a center at (0, 0). Point (0, negative 5) lies on the circle.
The point (0, 5) lies on a circle that is centered at the origin. Does (–3, –4) also lie on the circle?
Identify the radius from the graph.
r = units
Determine the distance from the center to
(–3, –4) using the distance formula.
distance = units
Compare the radius to the distance. Does the point (–3, –4) also lie on the circle?
