If a production possibility curve representing a trade-off between a grade in English and a grade in math has a negative slope, we know that:
A. there is a direct relationship between grades in English and grades in math.
B. there is no relationship between grades in English and grades in math.
C. there is an inverse relationship between grades in English and grades in math.
D. one can get better grades in English only if one gets better grades in math.
Answer:C
If a production possibility curve representing a trade-off between a grade in English and a grade in math has a negative slope, we know that:
A. there is a direct relationship between grades in English and grades in math. B. there is no relationship between grades in English and grades in math. C. there is an inverse relationship between grades in English and grades in math. D. one can get better grades in English only if one gets better grades in math.
Explanation: The negative slope of the production possibility curve implies that one can get better grades in English only by sacrificing better grades in math, which is an inverse relationship as opposed to a direct one.
