What is the constant of proportionality in a proportional relationship?

Back

The constant of proportionality (k) is the ratio of the dependent variable (y) to the independent variable (x) in a proportional relationship, expressed as y = kx.

Front

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

Back

A proportional relationship can be identified if the ratio of y to x is constant for all pairs of values in the table.

Front

What does the equation y = kx represent?

Back

This equation represents a proportional relationship where y is directly proportional to x, with k being the constant of proportionality.

Front

If y = 14x, what is the constant of proportionality?

Back

The constant of proportionality is 14.

Front

What is the form of a proportional relationship equation?

Back

The form of a proportional relationship equation is y = kx.

Front

In the equation y = 19.25x, what does 19.25 represent?

Back

19.25 represents the constant of proportionality (k) in the relationship.

Front

What is a proportional relationship?

Back

A proportional relationship is a relationship between two quantities where their ratio is constant.

Front

If k = 5, what is the equation of the proportional relationship?

Back

The equation is y = 5x.

Front

How do you find the constant of proportionality from a graph?

Back

The constant of proportionality can be found by determining the slope of the line that represents the relationship on the graph.

Front

What is the significance of the constant of proportionality in real-world situations?

Back

The constant of proportionality helps to understand how one quantity changes in relation to another, such as speed, density, or cost per item.
