Table 18 contains price-supply data and price-demand data for soybeans. Find a linear regression model for the price-supply data where x is supply (in billions of bushels) and y is price (in dollars). Do the same for the price-demand data. (Round regression coefficients to two decimal places.) Find the equilibrium price for soybeans.
