Explanation:

The Land Ordinance of 1785 was a U.S. federal law created to systematically survey and sell unoccupied public lands in the western territories (north of the Ohio River) to raise revenue and organize settlement. It did not address slavery in the original 13 states, interstate trade, or southern public lands.

settling public lands in the West.
