Answer:
the number of large plantations along the sea coast grew rapidly from 1750-1775.
Step-by-step explanation:
Since more slaves are doing the work and more are getting imported and the number of large plantations along the sea grew because large plantations mean wealthy planters meaning they are owning large plantations and along the sea is because they are along the sea so it is easier to let them work near the sea without traveling a long distance.
