Constant of Proportionality (Tables)

Front

What is the constant of proportionality?

Back

The constant of proportionality is the ratio between two proportional quantities, often represented as 'k' in the equation y = kx.

Front

How can you determine if a table is proportional?

Back

A table is proportional if the ratio of y to x is constant for all pairs of values.

Front

What does the equation y = kx represent?

Back

This equation represents a proportional relationship where 'k' is the constant of proportionality.

Front

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

Back

The constant of proportionality is 3.

Front

If a table shows the values (2, 6), (4, 12), (6, 18), is it proportional?

Back

Yes, it is proportional because the ratio of y to x is always 3.

Front

What is the constant of proportionality for the equation y = 1/2 x?

Back

The constant of proportionality is 1/2.

Front

Fill in the blank: If y = 5x, then when x = 4, y = ___.

Back

20.

Front

What is the constant of proportionality in the table: (1, 2), (2, 4), (3, 6)?

Back

The constant of proportionality is 2.

Front

If y = 2x, what happens to y when x is doubled?

Back

y will also double.

Front

What is the missing number if the table shows (3, 9), (4, __), (5, 15)?

Back

The missing number is 12.
