Which set of ordered pairs (x, y) could represent a linear function? A = {(-2,-4), (0, -2), (2,0), (4,3)}
B = {(-6,5), (-4,2), (-1, -1), (2, -4)}
C = {(0,9), (1,7), (2,5), (3, 2)}
D = {(-3,-1), (1,1), (5,3), (9,5)}

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

your answer is
