this is an imaginary line that separates the northern (free) states from the southern (slave) states in America...
The main goal was to keep the balance of free States in line with the slave States. There were two Missouri Compromises. The first one was in 1820 and the famous US politician, Henry Clay was the Speaker of the House of Representatives, and was the key figure in the Compromise debates. The second Missouri Compromise of 1850, had the goal of establishing a guideline for determining free and slave state status. The Fugitive Slave Act is considered part of this compromise.
Your question incomplete. The answer is the Missouri Compromise. It did not actually decree that states to the South of the line would be slave-states. But slavery would be legal there.

Almost. South of the line, new states could be slave states, but did not have to be.

The Mason-Dixon Line is the invisible line that historically separated the northern and southern states in the United States. It was surveyed in the 1760s and came to represent the cultural and political divide between the free states in the North and the slave states in the South.
