Question

who does price elasticity of demand be measured at different points on straight line method?​

Answer 1

Price elasticity of demand can be measured at different points on straight line method by:-

Another method of measuring price elasticity of demand is geometric method which is used when elasticity is measure at different point on straight line curve. Ed is straight line curve which is extend to both sides to touch to x and y axis.

B is the mid point which differs the demand curve into 2 equal section point A is located in the upper section and point C is located in low section.

According to point elasticity method, elasticity of demand is at any point is measured by dividing lower section of demand curve.

$\small{\sf Ed = \dfrac{lower \: section\: demand\: curve}{Uper\: section\: demand\: curve}}$
