This is a trick question. If there is a linear relation between the number of eggs Gaston Eats (Y) and the average productivity of a Hen (eggs per day/#hens) that relationship will be Y= a + bX..
We now that when X= 2 Y= 64. There are an infinite number of combinations of a and b that will ensure this. For instance b could be zero and a = 64. That way Gaston would Eat 64 eggs when X =1, X=2 or X=3. Another solution might be Gaston eats 32 + 16X. so when X=1 He eats 48 eggs and when X=2 he eats 64. To determine the two parameters of a linear relationship you need 2 observation.. Note that with two observation you can determine the productivity of the hens. You cannot determine the number of hens. To determine the number of hens you would need a third observation. The proportion of total eggs Gaston eats as a percentage of total eggs produced.
Hope this helps.
