Final answer:
An increase in the price of resource X will cause the supply curve for good Y to shift leftward, leading to an increase in the equilibrium price and a decrease in the equilibrium quantity of good Y.
Step-by-step explanation:
If the price of resource X, being vital to the production of good Y, increases, the supply curve for good Y will shift leftward. This is a result of the increased production costs discouraging firms from manufacturing the same quantity of good Y at the same price, thus causing a decrease in supply. This leftward shift in supply will lead to a rise in the equilibrium price of good Y, and a decrease in the equilibrium quantity of good Y.
