I can't get the correct answer to this problem.
Find all points having a ycoordinate of 3 whos distance from the point (1,2) is 13. Thank you!

Since the y difference is 5 (2(3)), the x difference must be 12 (5^{2}+12^{2}=13^{2}). The x coordinate must therefore be 13 or 11. (You've got 2 points  I am assuming we're working in a plane).
This is an elementary geometry problem. Why is it this forum?
