Elasticity Along A Linear Demand Curve

Study the following linear demand curve and decide whether it is relatively elastic, relatively inelastic, unitary elastic, or all of them:

It all depends on which part of the demand curve (price ranges) we are referring to. By just looking at it, we cannot tell whether it is relatively elastic, relatively inelastic or unitary elastic. In fact, depending on which part of the linear demand curve you are looking at, it could be all three of these – relatively inelastic, relatively elastic or unitary elastic.

Let's see why this is so.
