Constant of Proportionality Retest

Front

What is the constant of proportionality?

Back

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

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.

Front

If the constant of proportionality is 3, what is the value of y when x = 5?

Back

y = 3 * 5 = 15.

Front

What is the constant of proportionality in the equation y = 8x?

Back

The constant of proportionality is 8.

Front

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

Back

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

Front

If 5 phones are sold and the constant of proportionality is 43, how much money is earned?

Back

Total earnings = 43 * 5 = $215.

Front

What is the constant of proportionality if y = 3x?

Back

The constant of proportionality is 3.

Front

In the equation y = 16x, what does 16 represent?

Back

16 represents the constant of proportionality.

Front

If the constant of proportionality is 5, what is the value of y when x = 2?

Back

y = 5 * 2 = 10.

Front

What is the relationship between the constant of proportionality and the slope of a line?

Back

The constant of proportionality is equal to the slope of the line in a graph of y versus x.
