Find all points having an y-coordinate of -3 whose distance from the point (1,2) is 13.
----------------
That would be a circle.
Draw the picture; put the center at (1,2) and let the radius be 13.
-----
Pick any point on the circle and label it (x,y)
-------------------
Equation:
distance from center to (x,y) = 13
d^2 = (x-1)^2+(y-2)^2
d = sqrt[(x-1)^2+(y-2)^2]
