the Americas to Europe

Assuming you're talking about where the Transatlantic Trade started-- the answer would be England to Africa.

Explanation:

The trade started when Europeans brought goods (particularly weapons) to Africa, and traded them for slaves and goods.  The slaves (and various goods) were then taken to the Americas and traded for more goods.  Those goods were taken back to Europe. and the cycle continued.
