Hi, I need help learning how to calculate the slope and how to calculate elasticity between 2 points. I am unfamiliar with the formulas.

\fNote: Keep as much precision as possible during your calculations. Your final answer should be accurate to at least two decimal places. a) What is the slope of the demand curve? [Slope = 0 I b) What is the elasticity of demand between points a and b? [Elasticity of Demand = 0 l c) What is the elasticity of demand between points c and d? d) At what price is the elasticity of demand equal to 1? Price = $0 e) At what price would consumers spend the most on this product? Price = $0 f) Between what prices is demand elastic? [Between $0 and $0
