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

What is the constant of proportionality?

Back

The constant of proportionality is the constant value (k) that relates two proportional quantities in the equation y = kx.

Front

How do you identify a proportional relationship from a table?

Back

A proportional relationship can be identified in a table if the ratios of corresponding values are constant.

Front

What does the slope of a graph represent in a proportional relationship?

Back

The slope of a graph in a proportional relationship represents the constant of proportionality.

Front

What is the equation of a line that represents a proportional relationship?

Back

The equation of a line that represents a proportional relationship is y = kx, where k is the constant of proportionality.

Front

How can you determine if a graph is proportional?

Back

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

Front

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

Back

Proportional relationships have a constant ratio, while non-proportional relationships do not maintain a constant ratio.

Front

If y = 5x, what is the constant of proportionality?

Back

The constant of proportionality is 5.

Front

What does the term 'rate of change' refer to?

Back

The rate of change refers to how much one quantity changes in relation to another quantity, often represented as the slope in a graph.

Front

How do you write an equation from a proportional table?

Back

To write an equation from a proportional table, identify the constant of proportionality and use the form y = kx.
