What 2 partial products would you add to find 513 tumes 46

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.

Xis -1/2
y is 35/4.

Ibelieve the answer is b. y=0 would make the line horizontal across the x.
