Proportional Relationships and Equations

Front

What is the constant of proportionality?

Back

The constant of proportionality is the constant value (k) that relates two proportional quantities in a proportional relationship.

Front

What does k represent in the equation y = kx?

Back

k represents the constant of proportionality, which is the ratio of y to x in a proportional relationship.

Front

Write an equation for this relationship: If y increases by 5 for every increase of 1 in x.

Back

y = 5x

Front

If the constant of proportionality is 10, which of the following is the correct proportional equation?

Back

y = 10x

Front

What is the Constant of Proportionality of the Table? If the values are (1, 1/3), (2, 2/3), (3, 1)

Back

1/3

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

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

Back

To find the constant of proportionality, divide the y-value by the corresponding x-value for any pair of values.

Front

What is the graph of a proportional relationship?

Back

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

Front

If y = 3x, what is the constant of proportionality?

Back

The constant of proportionality is 3.

Front

What is the formula for finding y in a proportional relationship?

Back

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