Answer:
This a circle centered at the point
, and of radius "3" as it is shown in the attached image.
Step-by-step explanation:
Recall that the standard formula for a circle of radius "R", and centered at the point
is given by:

Therefore, in our case, by looking at the standard equation they give us, we extract the following info:
1)
since the radius must be a positive number and (
) is not a viable answer.
2)
for (
) to equal 
3)
for (
) to equal 
Therefore, we are in the presence of a circle centered at the point
, and of radius "3". That is what we draw as seen in the attached image.
To help you you should find a common denominator and then the fraction that has lower numbers is bigger
