Answer:
And the general formula for a circle is given by this expression:
With the center (h,k) and the radius r. If we compare this general expression with the formula that we obtain in (1) we see that :
So then the best solution for this cae would be:
b. center: (-1,1)
radius =4
Step-by-step explanation:
For this case we have the following equation given:
And we can complete the squares for this case like this:
Now we can rewrite the last expression like this:
