Trying to make an object move diagonally by clicking on it

You can tell by the title that this topic is self-explanatory but I’m working on a game mechanic where if i click on an image it moves diagonally to a different spot. Sounds simple except I’ve been trying to figure it out for the past 3 weeks and it’s driving me nuts. Please someone help me and show what I need to do.
-Thanks a bunch

You should look through the Labs examples here, specifically the Tween and Input sections.
