You're going to need 2,000,000 cups of milk. And you can see that this is a proportional relationship. To go from number of eggs to cups of milk, we indeed multiplied by two every time. That came straight from this equation.

Proportional relationships are a fundamental concept in mathematics, and they are often represented by the equation y = kx, where k is the constant of proportionality. This equation states that two quantities, x and y, are directly proportional to each other, meaning that they change at the same rate.In this video lesson we will learn about proportional linear relationships and slope.
