Proportional Relationships with Tables/Equations

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 quantity 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 constant.

Front

What does it mean if a table is not proportional?

Back

If a table is not proportional, it means that the unit rate is not constant across the values.

Front

What is the unit rate in a proportional relationship?

Back

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

Front

How do you write an equation for a proportional relationship?

Back

An equation for a proportional relationship can be written in the form y = kx, where k is the constant of proportionality.

Front

What is the constant of proportionality?

Back

The constant of proportionality is the constant value (k) that relates the two quantities in a proportional relationship.

What happens to a figure when the scale factor is greater than one?

Back

When the scale factor is greater than one, the new figure will be an enlargement of the original figure.

Front

What happens to a figure when the scale factor is less than one?

Back

When the scale factor is less than one, the new figure will be a reduction of the original figure.

Front

How can you identify the scale factor in a proportional relationship?

Back

The scale factor can be identified by dividing the new measurement by the original measurement.

Front

What is the relationship between proportional relationships and graphs?

Back

In a graph, a proportional relationship is represented by a straight line that passes through the origin.
