Front

What is a proportional relationship?

Back

A relationship between two quantities where the ratio of one quantity to the other is constant.

Front

What is the constant of proportionality?

Back

The constant ratio in a proportional relationship, often represented as 'k' in the equation y = kx.

Front

What is a unit rate?

Back

A comparison of two quantities where the denominator is always 1 unit.

Front

What is the formula for a proportional relationship?

Back

y = kx, where y is the dependent variable, k is the constant of proportionality, and x is the independent variable.

Front

How do you find the constant of proportionality from a table?

Back

Divide the value of one quantity by the corresponding value of the other quantity.

Front

If a table shows distances on a map and actual distances, what indicates a proportional relationship?

Back

The ratios of the distances should be constant.

Front

What does it mean if two quantities are directly proportional?

Back

As one quantity increases, the other quantity increases at a constant rate.

Front

What is an example of a proportional relationship in real life?

Back

The relationship between distance and time when traveling at a constant speed.

Front

How can you determine if a table represents a proportional relationship?

Back

Check if the ratios of corresponding values are equal.

Front

What is the significance of the unit rate in a proportional relationship?

Back

It helps to understand the relationship in terms of one unit, making comparisons easier.
