Does 3.2:8 and 1.2:3 form a proportion

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.

The answer will be y=-5+0 because the slope is -5 and the it has to go through y-axis 0
