Constant of Proportionality (Tables)

Front

What is the constant of proportionality?

Back

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

Front

Which equation represents the constant of proportionality?

Back

The equation that represents the constant of proportionality is y = kx.

Front

If a car travels 45 miles in 1 hour, what is the constant of proportionality in terms of speed?

Back

The constant of proportionality is 45 mph.

Front

Fill in the blank: The constant of proportionality is the ratio of y to x, expressed as ___.

Back

k = y/x.

Front

Determine the constant of proportionality for the table: If x = 1, y = 15; x = 2, y = 30; what is y in terms of x?

Back

y = 15x.

Front

What does the constant of proportionality tell us about the relationship between two variables?

Back

It indicates how much one variable changes in relation to another variable.

Front

If the constant of proportionality is 10, what is the value of y when x = 5?

Back

y = 10 * 5 = 50.

Front

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

Back

'k' represents the constant of proportionality.

Front

If y = 30 when x = 3, what is the constant of proportionality?

Back

k = y/x = 30/3 = 10.

Front

How can 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.
