The equation S=-0.5D+750 represents the relationship between the supply (S) and demand (D) for water in the united states. If the demand for water increases, what is the impact on the water supply?

If the demand for water increases, according to the equation S=-0.5D+750, the water supply will decrease. This is because as demand increases, the supply will need to decrease in order to maintain the balance between supply and demand as indicated by the equation.
