Review Proportional Relationships Tables, Graphs & Equaitons

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 quantity is constant.

Front

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

Back

A table represents a proportional relationship if the ratios of the values in the table are equivalent.

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 constant of proportionality?

Back

The constant of proportionality is the constant ratio between two proportional quantities, often represented by 'k'.

Front

If a graph passes through the origin, what can you conclude?

Back

If a graph passes through the origin, it indicates that the relationship is proportional.

Front

What does the point (1, 48) represent in a proportional relationship?

Back

The point (1, 48) means that for every 1 unit of the first quantity, there are 48 units of the second quantity.

Front

Write the equation for a proportional relationship given a constant of proportionality of 5.

Back

y = 5x

Front

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

Back

The slope of a line in a proportional relationship is equal to the constant of proportionality.

Front

How do you determine if a graph is linear?

Back

A graph is linear if it forms a straight line when plotted.

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 that the relationship is not proportional.
