Constant of Proportionality

Front

What is the constant of proportionality?

Back

The constant of proportionality is the constant value (k) that relates two proportional quantities, often represented as y = kx.

Front

How do you find the constant of proportionality for an equation?

Back

The constant of proportionality is the number in front of x in the equation y = kx.

Front

What does the point (0, 0) represent in a proportional relationship?

Back

The point (0, 0) is called the origin.

Front

In the equation y = kx, what does 'k' represent?

Back

'k' represents the constant of proportionality.

Front

What is the constant of proportionality for the relationship represented by the table: (1, 75), (2, 150), (3, 225)?

Back

k = 75

Front

True or False: The constant of proportionality can be negative.

Back

True, the constant of proportionality can be negative, indicating an inverse relationship.

Front

If the constant of proportionality is 2, what is the value of y when x = 3?

Back

y = 2 * 3 = 6.

Front

What is the relationship between proportionality and linear equations?

Back

Proportionality is a specific case of linear equations where the line passes through the origin.
