Answer:
Downward sloping
Explanation:
According to the law of demand, this law states that there is a inverse relationship between the price of a commodity and the quantity demanded for a commodity. This indicates that as the price of the commodity increases then as a result the quantity demanded for that commodity decreases and as the price of the commodity decreases then as a result the quantity demanded for that commodity increases.
Monopoly refers to the market conditions in which there is only a single firm operating in a whole market.
Hence, due to this inverse relationship between the price and the quantity demanded, the demand curve for a monopoly firm is downward sloping.
