Lesson(s) Review Mini Flashcard

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 a proportional graph look like?

Back

A proportional graph 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 of one quantity to another is not constant.

Front

How can you identify a non-proportional graph?

Back

A non-proportional graph does not pass through the origin and is not a straight line.

Front

What is the constant of proportionality?

Back

The constant of proportionality is the constant ratio between two proportional quantities, often represented as 'k' in the equation y = kx.

Front

If y = 3x, what is the constant of proportionality?

Back

The constant of proportionality is 3.

Front

What does the equation y = 8x represent?

Back

This equation represents a proportional relationship where for every increase of 1 in x, y increases by 8.

Front

How do you determine if a graph is proportional?

Back

To determine if a graph is proportional, check if it is a straight line that passes through the origin.

Front

What is the slope of a proportional graph?

Back

The slope of a proportional graph is equal to the constant of proportionality.

Front

If a graph shows the equation y = 1x, what can you say about it?

Back

This graph is proportional, and the constant of proportionality is 1.
