Constant of Proportionality Review

Front

What is the constant of proportionality?

Back

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

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

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 the equation y = kx represent?

Back

The equation y = kx represents a direct variation where y is directly proportional to x, with k being the constant of proportionality.

If y = 9 when x = 1, what is the constant of proportionality?

Back

The constant of proportionality is 9.

Front

What is the constant of proportionality if y = 16 when x = 1?

Back

The constant of proportionality is 16.

Front

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

Back

In the equation y = kx, k represents the constant of proportionality.

Front

If y = 2.5x, what is the value of x when y = 37.5?

Back

x = 15.

Front

What is the constant of proportionality if y = 10 when x = 1?

Back

The constant of proportionality is 10.

Front

How can you identify the constant of proportionality from a graph?

Back

The constant of proportionality can be identified from a graph by finding the slope of the line, which represents k.

Front

What is the relationship between x and y in a proportional relationship?

Back

In a proportional relationship, as x increases, y increases at a constant rate determined by the constant of proportionality.
