The animal shelter requires 1 pound of food for every 3 animals. This directly proportional relationship is represented by the equation y = (1/3)x, where x represents the number of animals and y represents pounds of food. If y varies directly with x, which graph represents the situation?
A graph has number of animals on the x-axis and food (pounds) on the y-axis. Points are at (0, 1), (2, 2), (4, 3), (6, 4), (8, 5), and (10, 6).
A graph has number of animals on the x-axis and food (pounds) on the y-axis. Points are at (0, 0), (3, 1), (6, 2), (9, 3).
