The slope of AB is - 5/3 segment CD has endpoint a C(-3, 10) and D(6,-5). Are AB and CD parallel, perpendicular or neither?

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
