By examining the budget line:

11+22=p1x1+p2x2=m

and consider an increase in income, explain why it is impossible to have both 1x1 and 2x2 to be inferior goods (regardless of the utility function).

By examining the budget line: P1361 + P2362 = m and consider an increase in income, explain why it is impossible to have both x1 and x2 to be inferior goods (regardless of the utility function)
