If supply is upward sloping,a decrease in demand with no change in supply will lead to a(n) _____ in equilibrium quantity and a(n) _____ in equilibrium price.

A) increase;increase
B) increase;decrease
C) decrease;increase
D) decrease;decrease

If there is a decrease in demand with no change in supply, this means that there will be an excess supply of goods, leading to a decrease in equilibrium quantity. Since the supply curve is upward sloping, this excess supply will put downward pressure on prices, leading to a decrease in equilibrium price. Therefore, the correct answer is D, decrease in equilibrium quantity and decrease in equilibrium price.
