Macbook as a 2nd monitor for an iMac

I wish to use a Macbook (13" Alum late 2008) 10.10.1 as a 2nd monitor for an iMac (20-inch, Mid 2007) 10.9.3 - what cord do I need - (if possible)

iMac, Mac OS X (10.6.8)

I don't know what happened! My answer is gone!

Anyway...if you connect a second display and open the Display preference pane you should see an "Arrangement" tab. Click that and you can drag the little white menu bar from one screen to the other to choose which one you want as the main screen. There will also be a box at the bottom of the window that you can check to Mirror the displays.
