Front

What is the constant of proportionality?

Back

The constant of proportionality is a constant value that relates two proportional quantities. It is often represented by 'k' in the equation y = kx.

Front

How do you find the constant of proportionality from a table of values?

Back

To find the constant of proportionality from a table, divide the value of the dependent variable by the value of the independent variable for any pair of corresponding values.

Front

If k = 5, what does this indicate about the relationship between the variables?

Back

If k = 5, it indicates that for every unit increase in the independent variable, the dependent variable increases by 5 units.

Front

What does it mean if the constant of proportionality is 1?

Back

If the constant of proportionality is 1, it means that the two variables are equal; for every unit increase in one variable, the other variable increases by the same amount.

Front

What is the constant of proportionality for the equation y = 2x?

Back

The constant of proportionality is 2.

Front

How can you determine if a relationship is proportional?

Back

A relationship is proportional if the ratio of the dependent variable to the independent variable is constant.

Front

What is the constant of proportionality for the equation y = rac{2}{3}x?

Back

The constant of proportionality is rac{2}{3}.

Front

If a graph shows a straight line passing through the origin, what can be said about the relationship?

Back

If a graph shows a straight line passing through the origin, the relationship is proportional.

Front

What does a negative constant of proportionality indicate?

Back

A negative constant of proportionality indicates an inverse relationship; as one variable increases, the other decreases.

Front

How do you interpret the slope of a line in a proportional relationship?

Back

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