Proportional v. Non-Proportional Relationships

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 is a non-proportional relationship?

Back

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

Front

How do you determine if a relationship is proportional from a table?

Back

If the ratios of corresponding values are equal, the relationship is proportional.

Front

What does the unit rate represent in a proportional relationship?

Back

The unit rate represents the constant ratio between two quantities, often expressed as 'k'.

Front

What is the y-intercept in a graph?

Back

The y-intercept is the point where the graph crosses the y-axis, indicating the value of y when x=0.

Front

How can you identify a proportional relationship from a graph?

Back

A proportional relationship will show a straight line that passes through the origin (0,0).

Front

What does it mean if a graph has a y-intercept other than zero?

Back

If a graph has a y-intercept other than zero, it indicates a non-proportional relationship.

Front

What is the formula for finding the unit rate?

Back

The unit rate can be found by dividing the value of one quantity by the value of the other quantity.

Front

If k = 3 in a proportional relationship, what does this mean?

Back

It means that for every 1 unit of the first quantity, there are 3 units of the second quantity.

Front

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

Back

The slope represents the constant rate of change between the two quantities.
