What is a proportional relationship?

Back

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

Front

How can you identify a proportional relationship from an equation?

Back

If the equation can be expressed in the form y = kx, where k is a constant, it represents a proportional relationship.

Front

What is the constant of proportionality?

Back

The constant of proportionality (k) is the constant factor that relates two proportional quantities.

Front

What is the formula to find the constant of proportionality?

Front

What does unit rate mean?

Back

Unit rate is a comparison of two different quantities when they are combined together, expressed as a quantity per one unit.

Front

How do you find the unit rate from a proportional relationship?

Back

Divide the total quantity by the number of units to find the unit rate.

Front

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

Back

An example is the relationship between distance and time when traveling at a constant speed.

Front

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

Back

If the ratios of the corresponding values in the table are constant, it represents a proportional relationship.

Front

What is the significance of the slope in a graph of a proportional relationship?

Back

The slope represents the constant of proportionality (k) in a graph of a proportional relationship.

Front

What happens to the graph of a proportional relationship when k is positive?

Back

The graph will be a straight line that passes through the origin and slopes upwards.
