public education.

slavery.

taxation.

the development of colonies.

Explanation:

The Land Ordinance of 1785 established a system for surveying and selling western lands, which directly supported the development and settlement of new colonial-style territories in the U.S. It set aside land for public education but did not promote it as a core focus; it did not endorse slavery, and while it involved land sales, its primary impact was territorial development.

Answer:

the development of colonies.
