You are baking a cake. For every three cups of flour, you need to add two eggs. Write an equation for the relationship between the number of eggs, y , and the amount of flour, x . Distinguish whether this is a proportional or nonproportional situation.

The equation for the relationship between the number of eggs (y) and the amount of flour (x) is:

y = (2/3)x

This is a proportional situation because the relationship between the number of eggs and the amount of flour is constant (2 eggs for every 3 cups of flour).
