Group of answer choices reflects a direct relationship between the price and quantity. The Law of Supply: a) shows that the relationship between producer revenue and quantity supplied is negative b) reflects the income and substitution effects of a price change c) is reflected in a downsloping supply curve.

c) is reflected in a downward sloping supply curve.

Explanation:

A direct relationship between the price and quantity is reflected in a downward sloping supply curve.

The Law of demand states that ''conditional on all else being equal, as the price of a good increases, quantity demanded decreases; conversely, as the price of a good decreases, quantity demanded increases"

Hence this relationship is reflected in a downward sloping curve as demand falls as price rises.
