- Geometry equation of circles -
**Steve**, Saturday, March 1, 2014 at 5:52amthe two lines are 5 apart, so the radius is 5/2, with the center at (7/2,k) so

(x - 7/2)^ + (y-k)^2 = (5/2)^2

The point (2,2) is on the line, so

(2 - 7/2)^2 + (2-k)^2 = (5/2)^2

k = 0 or 4

(x - 7/2)^2 + (y-4)^2 = (5/2)^2

(x - 7/2)^2 + y^2 = (5/2)^2

So, the question is misleading. There are two circles that fit the conditions:
