Let
x--------> the first quantity
y------> the second quantity
q------> the quotient
So
-------> equation 1
in this problem

Substitute the values in the equation 1

Simplify

therefore
<u>the answer is</u>
The quotient is equal to 
When you write the equation of a circle in the form

Then the center of the circle has coordinates
and the radius is 
So, in your case, the center of the circle is
