Front

What is the constant of proportionality?

Back

The constant of proportionality is the ratio between two proportional quantities, often represented as 'k'. It can be found by calculating the unit rate.

Front

How can you find the constant of proportionality?

Back

You can find the constant of proportionality by determining the unit rate of the two quantities being compared.

Front

What does a proportional graph look like?

Back

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

Front

What is a unit rate?

Back

A unit rate is a ratio that compares a quantity to one unit of another quantity.

Front

If k = 5, what does this mean in terms of proportionality?

Back

It means that for every 1 unit of the independent variable, the dependent variable increases by 5 units.

Front

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

Back

Proportional relationships have a constant ratio (constant of proportionality), while non-proportional relationships do not maintain a constant ratio.

Front

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

Back

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

Front

What is the significance of the origin in a proportional graph?

Back

The origin (0,0) indicates that when the independent variable is zero, the dependent variable is also zero, which is a key characteristic of proportional relationships.

Front

If a graph is not a straight line, what can you conclude?

Back

If a graph is not a straight line, it indicates that the relationship between the variables is non-proportional.

Front

What does it mean if k = 1/5?

Back

It means that for every 5 units of the independent variable, the dependent variable increases by 1 unit.
