b$.$ Use the midpoint formula for $E_d$ to determine price elasticity of demand for each of the four possible $$1$ price changes.

Moving from $$5$ to $$4,E_d=$

Moving from $$4$ to $$3,E_d=$

Moving from $$3$ to $$2,E_d=$

Moving from $$2$ to $$1,E_d=$

c$.$ What can you conclude about the relationship between the slope of this demand curve and its elasticity?

The demand curve has a constant slope of $,$ and its elasticity as we move down the curve.

d$.$ Explain why demand is elastic in the northwest segment of the demand curve and inelastic in the southeast segment.
