Assume that a 6 percent increase in income in the economy produces a 3 percent increase in the quantity demanded of Good X. The coefficient of income elasticity of demand is
positive, and therefore X is a normal good.

can be represented by a line parallel to the horizontal axis.
A perfectly inelastic demand schedule
can be represented by a line parallel to the vertical axis.
Firms are motivated to minimize production costs because
competitive pressures in the market will drive out higher-cost producers.
the cross elasticity of demand for Product X with respect to the price of Product Y is −1.2. It can be inferred that X and Y are
complementary products.
An increase in the price of a product will reduce the amount of it purchased because
consumers will substitute other products for the one whose price has risen.

price and quantity demanded are inversely related.
the demand curve shows the relationship between
price and quantity demanded.
The supply curve shows the relationship between
price and quantity supplied.

decrease equilibrium price and increase equilibrium quantity.
