You can  put this solution on YOUR website! The point (3, y) is equidistant from the point (10, 3) and (-5, -1). Find the value of y.  
================= 
From (3,y) to (10,3): 
  
---- 
From (3,y) to (-5,-1): 
  
---- 
From (3,y) to (10,3): 
  
8y = -7 
y = -7/8 
-------------- 
Another approach: 
Find the perpedicular bisector of the line between the 2 points, then find y when x = 3.
