7. Circles in the Coordinate Plane
Sign In
Adapt the given equation to match the standard equation of a circle.
Center: (- 5,3)
Radius: 3
Graph:
Here, the center is the point ( h, k) and the radius is r. We will rewrite the given equation to match this form, and then we can identify the center and the radius. (x+5)^2+(y-3)^2=9 ⇕ (x-( - 5))^2+(y- 3)^2= 3^2
The center of the circle is the point ( - 5, 3), and its radius is 3. Finally, we can graph the circle using this information.
