Equations for proportional relationships.

1. Proportional Relationships: The Basics. First, we must revisit the concept of proportional relationships. As you may recall, a proportional relationship exists when the ratio of two variables is constant. For instance, if you earn \($10\) for every hour you work, then your earnings and hours worked have a proportional relationship. 2. Write the equation of the proportional relationship. y = kx y = k x. Substitute the given x x and y y values, and solve for k k . 30 = k ⋅ 6 30 = k ⋅ 6. k = 5 k = 5. The equation is y = 5x y = 5 x . Now substitute x = 100 x = 100 and find y y . y = 5 ⋅ 100 y = 500 y = 5 ⋅ 100 y = 500. Direct variation describes a simple relationship ...

ExponentsAug 15, 2020 · When two quantities x and y are in a proportional relationship, we can write the equation y = kx and say, “ y is proportional to x .”. In this case, the number k is the corresponding constant of proportionality. We can also write the equation x = 1 ky and say, “ x is proportional to y .”. 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.When two quantities x and y are in a proportional relationship, we can write the equation y = kx and say, “ y is proportional to x .”. In this case, the number k is the corresponding constant of proportionality. We can also write the equation x = 1 ky and say, “ x is proportional to y .”. Write the equation of the proportional relationship. y = kx y = k x. Substitute the given x x and y y values, and solve for k k . 30 = k ⋅ 6 30 = k ⋅ 6. k = 5 k = 5. The equation is y = 5x y = 5 x . Now substitute x = 100 x = 100 and find y y . y = 5 ⋅ 100 y = 500 y = 5 ⋅ 100 y = 500. Direct variation describes a simple relationship ... Rates & proportional relationships. The unit rate of change of y with respect to x is the amount y changes for a change of one unit in x .
