Answer 1

The answer is x^2+y^2-6x-16=0

Explanation:

I just took the test and got it correct

Answer 2

Based on the graph, we know that the center of the circle is at (3,0) and its radius is 5. We can plug this into the standard form of the equation:

(x-3)²+y²=25

We can expand this to put it into general form:

x²-6x+9+y²=25
x²+y²-6x-16=0
