Monroe consumes crab cakes and tuna. monroe's utility increases with the consumption of crab cakes, but his utility neither increases nor decreases with the consumption of tuna. assuming tuna is on the x-axis and crab cake is on the y-axis, what do monroe's indifference curves look like?

The indifference curve will be mostly like Horizontal lines because the y-axis is the one who is increasing and the x-axis is the one decreasing so in my assumptions it will be horizontal. The indifference curve is the curve on the graph that represent two commodities to know the satisfaction of the buyer.
