How did the missouri compromise impact the expansion of slavery into the territories?

The Missouri Compromise was an agreement arranged in 1820 between the northern and southern states. It consisted in granting the state of Missouri a slave status in exchange for the consent of the southern states that the western border of slavery would run along the 36° 30' parallel, whereas the border between free and slave states in the East of the continent was drawn along the Mason-Dixon Line and the Ohio River. In addition, a new state - Maine - was separated from Massachusetts to maintain a balance of power in the Senate between slave states and non-slavery states.
