9. Company ACME produces output q using inputs K and L, which are perfect complements. To produce one unit of output q, the rm needs to use 1/4 of a unit of labor and 1/6 of a unit of capital. Given the currently prices I of K and W of L, the company is optimally choosing K* and L* to minimize the cost of producing q. The graph below represents one of the isogost lines of ACME. The optimal mix of K* and L* must be
