Constant of Proportionality (Test Prep)

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

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 y by the corresponding value of x for any pair of values.

Front

What does a proportional graph look like?

Back

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

Front

If y = kx, what does 'k' represent?

Back

'k' represents the constant of proportionality, which is the unit rate of change between x and y.

Front

True or False: The constant of proportionality can change depending on the values of x and y.

Back

False. The constant of proportionality remains the same for a given relationship.

Front

What is the unit rate in a proportional relationship?

Back

The unit rate is the constant of proportionality expressed as a ratio of y to x when x = 1.

Front

In the equation y = ½x, what is the constant of proportionality?

Back

1/2.

Front

Which formula is used to calculate the constant of proportionality?

Back

k = y/x.

Front

If the constant of proportionality is 3, what is the equation of the proportional relationship?

Back

y = 3x.

Front

What does it mean if a graph is not proportional?

Back

If a graph is not proportional, it does not form a straight line through the origin.
