Constant of Proportionality

The constant of proportionality is the ratio between two proportional quantities, often represented as 'k'. It remains constant as the values change.

To find the constant of proportionality from a table, divide the value of one quantity by the corresponding value of the other quantity.

208 calories per serving.

A table is proportional if the ratio of the values in one column to the values in another column is constant.

If 2 apples cost $4, then 4 apples cost $8. The constant of proportionality is $2 per apple.

k = y/x, where y is the dependent variable and x is the independent variable.

Yes, it is proportional because the ratio of y to x is constant (2).

The constant of proportionality is 45 mph.

It represents a proportional relationship.

A non-proportional relationship does not have a constant ratio between the two quantities.
