Best ResponseYou've already chosen the best response.0Let D be the demand and P the price. Then D(100) = 6.7 and D(80) = 10.2. The slope is (10.26.7)/(80100) = 0.175. So using the pointslope formula, the line is D(P) = 0.175 (P80) + 10.2. When P=75, the demand is D(75) = 0.175 (5) + 10.2 = 11.075 million.
