Proportional or Nonproportional

Front

What is the constant of proportionality?

Back

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

Front

Which line shows a proportional relationship between x and y?

Back

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

Front

Is the graph proportional or non-proportional?

Back

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

Front

What is the constant of proportionality (in miles per hour) based on the table?

Back

The constant of proportionality can be found by dividing the dependent variable by the independent variable for any pair of values.

Front

Which graph is non-proportional?

Back

A non-proportional graph may show a curve or a straight line that does not pass through the origin.

Front

Define proportional relationship.

Back

A proportional relationship is one where two quantities maintain a constant ratio to each other.

Front

What is an example of a proportional relationship in real life?

Back

An example is the relationship between distance and time when traveling at a constant speed.

Front

What does it mean if a relationship is non-proportional?

Back

A non-proportional relationship means that the ratio between the two quantities changes.

Front

How can you identify a proportional relationship from a table of values?

Back

If the ratio of y to x is constant for all pairs of values, the relationship is proportional.

Front

What is the formula for finding the constant of proportionality?

Back

The formula is k = y/x, where k is the constant of proportionality.
