Question

a vertical supply curve is said to be ______. (1 point) relatively inelastic relatively elastic perfectly elastic perfectly inelastic

Explanation:

A vertical supply curve means the quantity supplied does not change at all regardless of price changes. This matches the definition of perfectly inelastic supply, where the price elasticity of supply equals 0. Relatively inelastic supply has a non-vertical, steep curve; relatively elastic and perfectly elastic supply curves are upward-sloping or horizontal respectively.

Answer:

perfectly inelastic
