Identifying Proportional Relationships (tables)

Front

What is the constant of proportionality?

Back

The constant of proportionality is the ratio between two proportional quantities, often represented as k in the equation y = kx.

Front

Which statement best describes the relationship of x and y in the table?

Back

Proportional means that as one quantity increases, the other quantity increases at a constant rate.

Front

Is this table proportional?

Back

A table is proportional if the ratio of y to x is constant for all pairs of values.

Front

What is the constant of proportionality?

Back

The constant of proportionality can be found by dividing y by x for any pair of values in a proportional relationship.

Front

Is the given table a proportional relationship? If so, what is the constant of proportionality?

Back

If the ratios of y to x are the same for all pairs, then it is proportional, and the constant can be identified.

Front

What does it mean for two quantities to be proportional?

Back

Two quantities are proportional if they maintain a constant ratio or relationship to each other.

Front

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

Back

Check if the ratios of y to x are the same for all pairs of values in the table.

Front

What is an example of a proportional relationship?

Back

An example is the relationship between distance and time at a constant speed, such as 60 miles per hour.

Front

What is the formula for finding the constant of proportionality?

Back

The formula is k = y/x, where k is the constant of proportionality.

Front

If y = 4x, what is the constant of proportionality?

Back

The constant of proportionality is 4.
