In many realβworld situations a variable y changes in direct proportion to another variable x, meaning the ratio y/x remains constant.
This unchanging ratio is called the constant of proportionality and is usually denoted by k.
To find k you rearrange the proportional relationship y = kx, giving k = \frac{y}{x}. Once k is known, you can predict y for any x.
