The Attempt at a Solution

Just wondering whether i have done it right?
So the Thevenin circuit has a voltage supply of 12V, in series with an 8 Ohm resistor, while the Norton circuit has a current supply of 1.5A in parallel with an 8 Ohm resister.

Ok my tutor just said that it's right...however since I'm a very paranoid person, i'd like a second opinion, just to reaffirm :)
