How was the tariff and the issue of slavery connected?

Both created strong sectional differences. The tariff sectioned out the south from the north. Slavery divided African Americans and other races from Caucasians.

.  Now the answers on your paper do not have this choice, but if you think about it, (2-x)=-1(x-2) and (1-x)=-1(x-1).  This means that when you have (2-x)/(1-x), this also equals to (x-2)/(x-1), since the -1's cancel out.  So, the answer is D.

I hope this was helpful!
