6. Explain precisely, what types of goods are X and Y for the consumer, whose preferences are described by utility function U(x;y) = 2x + y. Does the consumer consume X and Y always together (in what ratio?) or are X and Y perfect substitutes (substitutable at what rate?) or non-perfect substitutes for the consumer?
