Proportional or Non-Proportional (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

What is a non-proportional relationship?

Back

A non-proportional relationship is a relationship between two quantities where the ratio is not constant.

Front

How can you identify a proportional table?

Back

A table is proportional if the ratios of corresponding values are equal.

Front

How can you identify a non-proportional table?

Back

A table is non-proportional if the ratios of corresponding values are not 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

If a table shows 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

If a table shows values (1, 2), (2, 5), (3, 7), is it proportional?

Back

No, it is non-proportional because the ratios are not constant.

Front

What does a graph of a proportional relationship look like?

Back

A graph of a proportional relationship is a straight line that passes through the origin.

Front

What does a graph of a non-proportional relationship look like?

Back

A graph of a non-proportional relationship is a straight line that does not pass through the origin.

Front

Can a proportional relationship have a zero value?

Back

Yes, a proportional relationship can have a zero value, as both quantities can be zero.
