Unicorn PRETEST - Proportional vs NonProportional

Front

What is a proportional relationship?

Back

A proportional relationship is a relationship between two quantities where their ratio is constant.

Front

What does it mean if a graph is proportional?

Back

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

Front

What is a non-proportional relationship?

Back

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

Front

How can you identify a proportional graph?

Back

A proportional graph can be identified by a straight line that passes through the origin.

Front

What is the significance of the point (0,0) in proportional graphs?

Back

The point (0,0) indicates that when one quantity is zero, the other quantity is also zero, which is a characteristic of proportional relationships.

Front

What does a curvy line on a graph indicate?

Back

A curvy line on a graph indicates a non-proportional relationship.

Front

If a graph passes through (12,12), is it proportional?

Back

Yes, because it is a straight line that passes through the origin.

Front

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

Back

Proportional graphs are straight lines through the origin; non-proportional graphs do not follow this rule.

Front

Can a graph be proportional if it does not pass through the origin?

Back

No, a graph must pass through the origin to be considered proportional.

Front

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

Back

An example is the relationship between distance and time at a constant speed.
