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 the formula for a proportional relationship?

Back

y = kx, where k is the constant of proportionality.

What does it mean if a graph passes through the origin?

Back

If a graph passes through the origin (0,0), it indicates that the relationship is proportional.

Front

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

Back

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

What does a linear graph indicate about a relationship?

Back

A linear graph indicates a constant rate of change between the two variables.

Front

What is the significance of the slope in a proportional relationship?

Back

The slope represents the constant of proportionality (k) in the equation y = kx.

Front

Can a graph be linear but not proportional?

Back

Yes, a graph can be linear but not proportional if it does not pass through the origin.
