Answer:
Northerners who didn’t want slavery in the new territories did not support the Missouri compromises
Step-by-step explanation:
The Missouri Compromise created a separation between Free states and slave states. The compromise proposed that the regions below the southern border of Missouri will be considered as slave states and the regions above the southern border will be considered as free states.
This will automatically turn several territories acquired from Louisiana purchased to be turned into slaves states.
Because of this Northerners who were against slavery completely against the implementation of the compromise.
