So you are looking to see if the player can see the enemy or vica verse?

Yes, or more importantly, if an enemy can fire a shot without it being blocked by a wall. 

I apologize for not being too clear on this topic.  Let's say that the slope between the enemy and the player is 2/1.  The enemy is at (100, 100), and the player is at (103, 106).  So the calculator checks (101, 102).  Is there a wall?  No.  Check (102, 104).  Is there a wall?  YES!  So the enemy cannot harm the player.
