Constant of Proportionality

Front

What is the constant of proportionality?

Back

The constant of proportionality is a constant ratio or factor that relates two proportional quantities. It is often represented by 'k' in the equation y = kx.

Front

Express the constant of proportionality in the equation y = kx when k = 15.

Back

y = 15x

Front

What is the constant of proportionality for the graph where y increases by 40 when x increases by 1?

Back

The constant of proportionality is 40.

Front

Identify the constant of proportionality if k = 1.50 in the equation y = kx.

Back

k = 1.50 means that for every unit increase in x, y increases by 1.50.

Front

What is the constant of proportionality if the graph shows a straight line passing through the origin with a slope of 16?

Back

The constant of proportionality is 16.

Front

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

Back

The constant of proportionality is 9.

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

What does it mean if the constant of proportionality is 0?

Back

If the constant of proportionality is 0, it means that y does not change as x changes; y is always 0.

Front

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

Back

'k' represents the constant of proportionality, which is the ratio of y to x.

Front

If the constant of proportionality is 2, what is the relationship between x and y?

Back

For every unit increase in x, y increases by 2.
