A man is trying to enclose a round pasture. He has 150 feet of fence. How big(area) of a pasture can he enclose?

It has a slope of 1 nd a y intercept of -2

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.
