Proportional Graph

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 does it mean for a graph to be proportional?

Back

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

Front

What is the significance of the origin in proportional graphs?

Back

The origin (0,0) is significant because a proportional graph must pass through it, indicating that when one quantity is zero, the other is also zero.

Front

What is a non-proportional relationship?

Back

A non-proportional relationship is when the ratio between two quantities is not constant, and the graph does not pass through the origin.

Front

How can you identify a proportional graph?

Back

You can identify a proportional graph by checking if it is a straight line that goes through the origin.

Front

What does a straight line on a graph indicate?

Back

A straight line on a graph indicates a constant rate of change between the two variables.

Front

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

Back

An example of a proportional relationship is the relationship between distance and time when traveling at a constant speed.

Front

What is an example of a non-proportional relationship?

Back

An example of a non-proportional relationship is the relationship between the number of items purchased and the total cost when there is a fixed fee added.

Front

What does it mean if a graph does not go through the origin?

Back

If a graph does not go through the origin, it indicates that there is a starting value or fixed cost, making it non-proportional.

Front

What is the slope of a proportional graph?

Back

The slope of a proportional graph represents the constant rate of change between the two variables.
