Suppose We Postulate a Linear Demand Curve and Observe, Through $\mathrm { A } , \mathrm { P } ^ { \mathrm { A } } = 2$

Multiple Choice

Suppose we postulate a linear demand curve and observe, through supply shifts, two points on the demand curve. At point $\mathrm { A } , \mathrm { P } ^ { \mathrm { A } } = 2$ and $\mathrm { Q } ^ { \mathrm { AA } } = 6$ . At point $\mathrm { B } , \mathrm { P } ^ { \mathrm { B } } = 4$ and $\mathrm { Q } ^ { \mathrm { dB } } = 2$ . The choke price for this demand curve is

A) 10
B) 2
C) 5
D) $- 2$
