Step-by-step explanation:
Equation of a circle:
The equation of a circle with center
is given by:

In which r is the radius.
Center (-14, -3)
This means that 
So



Passes through the point (-5,3),
This means that when
. We use this to find the radius squared. So



So, the equation of the circle is:


1500 is minus 1/10 after it is at 1700 thousad
