Answer:
Elasticity is independent of the units of measurement.
Step-by-step explanation:
Elasticity in economics, is a term that describes the measurement of the percentage change of one economic variable in response to a change in another economic variable.
Unlike the slope of the demand curve which measures the steepness or flatness of a line in terms of the measurement units for price and quantity. Elasticity on the other hand, has the advantage of being a unitless ratio, independent of the type of quantities being varied, which in turn simplifies data analysis.
Hence, Economists use elasticity to measure the responsiveness of quantity to a change in price rather than the slope of the demand curve because elasticity is independent of the units of measurement
