The graph shows the amounts of almonds (a), in grams, for different amounts of oats (o), in cups, in a granola mix. Select all of the true statements.

• This graph does not represent a proportional relationship.

• The equation o = 25a represents the proportional relationship in the graph.

• The constant of proportionality is 25.

• For every 3 grams of almonds, there are 75 cups of oats.

• If the graph was extended, the point (6,150) would be on this line.
