Proportional Relationships in Tables

Front

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 determine if a table represents a proportional relationship?

Back

A table represents a proportional relationship if the ratios of the corresponding values are equal.

Front

What is the constant of proportionality?

Back

The constant of proportionality is the constant ratio in a proportional relationship, often represented as 'k'.

Front

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

Back

You find the constant of proportionality by dividing one quantity by the corresponding quantity.

Front

What is the unit rate?

Back

The unit rate is the ratio of two measurements in which the second quantity is one unit.

Front

If a table shows the values (2, 4), (3, 6), (4, 8), is it proportional?

Back

Yes, it is proportional because the ratio of y to x is constant (2:1).

Front

What does it mean if a table is not proportional?

Back

If a table is not proportional, the ratios of the corresponding values are not equal.

Front

Can a proportional relationship be represented by a straight line on a graph?

Back

Yes, a proportional relationship can be represented by a straight line that passes through the origin on a graph.

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

If the unit rate is 5, what does that mean?

Back

It means that for every 1 unit of the second quantity, the first quantity increases by 5.
