the distance from (0,3) to the vertical line x = 27 is 27 ... 1/3 of that distance is 9.

now, what do you call the set of all points that are a distance 9 from the point (0,3) , and further ... what is its equation?

also, contrary to what you may think, this is not advanced algebra ... in future, post a problem like this in the Precalculus forum.
