Test 13 (Prop/Non-Prop)

Front

What is a proportional relationship?

Back

A proportional relationship is one where two quantities maintain a constant ratio or relationship to each other.

Front

What is a non-proportional relationship?

Back

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

Front

How can you identify a proportional relationship in a graph?

Back

In a graph, a proportional relationship is represented by a straight line that passes through the origin.

Front

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

Back

If a graph does not pass through the origin, it indicates a non-proportional relationship.

Front

What is the formula to determine if a relationship is proportional using a table?

Back

Divide y by x; if the result is constant for all pairs, the relationship is proportional.

Front

What does it mean if the ratio of y to x is constant?

Back

If the ratio of y to x is constant, it indicates a proportional relationship.

Front

What is an example of a proportional relationship?

Back

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

Front

What is an example of a non-proportional relationship?

Back

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

Front

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

Back

Look for a constant ratio between corresponding values of x and y.

Front

What is the significance of the origin in proportional relationships?

Back

The origin (0,0) represents the starting point where both quantities are zero in a proportional relationship.
