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

Back

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

Front

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

Back

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

Front

What is the unit rate in a proportional relationship?

Back

The unit rate is the constant of proportionality, representing how much one quantity changes for each unit of another quantity.

If the point (3, 12) is on a graph, what does it represent?

Back

It represents that for every 3 units of the first quantity, there are 12 units of the second quantity.

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

Back

The slope of the line in a proportional relationship graph is equal to the constant of proportionality.

Front

How do you find the constant of proportionality from a graph?

Back

You can find the constant of proportionality by determining the slope of the line, which is the change in y divided by the change in x.

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

Back

If a table does not pass through the origin, it indicates that the relationship is not proportional.
