Answer:
The locus is (x + 6)^2 + (y - 9)^2 = 100
Step-by-step explanation:
This is a circle with center (-6,9) and radius 10 units.
The general equation of a circle with center (a, b) and radius r is
(x - a)^2 + (y - b)^2 = r^2 so we insert the given values into this general equation to get the locus.
