PAR 4.3 (identify proportional relationships)- REMEDIATION

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 identify a proportional relationship on a graph?

Back

A proportional relationship on a graph is identified by a straight line that passes through the origin (0,0).

Front

What does it mean if a graph does not pass through the origin?

Back

If a graph does not pass through the origin, it indicates a non-proportional relationship.

Front

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

Back

A constant rate means that for every unit increase in one quantity, there is a consistent increase in the other quantity, indicating a proportional relationship.

Front

How can you determine if a set of data points represents a proportional relationship?

Back

You can determine if a set of data points represents a proportional relationship by checking if the ratios of corresponding values are equal.

Front

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

Back

An example of a proportional relationship in real life is the relationship between distance and time when traveling at a constant speed.

Front

What is the formula for a proportional relationship?

Back

The formula for a proportional relationship can be expressed as y = kx, where k is the constant of proportionality.

Front

What does the constant of proportionality represent?

Back

The constant of proportionality represents the ratio between two proportional quantities.

Front

How can you tell if a relationship is proportional from a table of values?

Back

A relationship is proportional if the ratios of the corresponding values in the table are constant.

Front

What is the difference between proportional and non-proportional relationships?

Back

Proportional relationships have a constant ratio and pass through the origin, while non-proportional relationships do not have a constant ratio and do not pass through the origin.
