Hint to finding solution
(a) Find the slopes for demand and supply using the point (x,p) given in the table
(b) Use point slope equation substituting the slope obtained and one point (x,p) to
obtain the requires demand and supply equations respectively.
(c) Graph the two equations, The point (x,p) the two lines meet is the equilibrium
point meaning when Demand = Supply. (x,p)

Supply is a schedule which shows the various amounts of a product sellers are at each price in a series of possible prices during a specified period, other things being equal. Supply portrays relationship between ( related either in the table or in the (graph). ) and ( ) to produce and offer for sale ) and ( ), they are (directly, inversely) S Describe and give a reason for the law of supply. The law of supply indicates that producers will produce and sell (more, less ) of their product at a high price than at a low price. This means that there is a positive, negative ) relationship between price and quantity supplied. The basic explanation is that, given product costs, a higher price means greater profits and thus more incentive for business to increase the quantity supplied.arrow_forward
