Find the center and radius of circle and sketch its graph: (x+3)2 + (y-4)2 = 25 I'm having trouble sketching the circle and not sure how to do the correct radius. Is it from the center or the origin?
Added by Destiny L.
Step 1
The equation is already in the standard form for a circle, which is: $(x-a)^2 + (y-b)^2 = r^2$ Where $(a, b)$ is the center of the circle and $r$ is the radius. In our case, we have: Show more…
