Answer:
L-shaped, beginning at 2PB and 1J
Explanation:
Indifference Curve is the graph representing product combinations, which give consumers the same level of satisfaction. Its slope is Marginal Rate of substitution (MRS), which implies sacrifise of a good to gain other good, satisfaction level remaining same.
Perfect Complements are the goods, used jointly to satisfy a particular consumer want, in a particular ratio.
John eats peanut butter & jelly in a particular proportion of (2:1) ; this implies that these are perfectly complementary goods for John.
Perfect Complements have right angled or L shape indifference curve. Their slope i.e MRS = 0. Such, as the goods have zero substitutability, no amount of good one will be sacrifised to gain any amount of good two. They would only be used in a particular ratio, represented by a ray from origin, L mid point.
And the 'L curve' coordinates depend on the fixed ratio of their complementary use. So, it would be (PB,J) = (2,1)
