It is the constant of proportionality.
proportion
The number of dollars is directly propotional to the number of pounds
Neither. Many items of expenditure would be shared (eg housing, utilities, transport, holidays) so the proportion would not be direct. But it would be closer to direct than inverse.
Such a number is called a "constant". If the number appears in front of a variable, it is sometimes called a "coefficient".

The relationship between two variables whose ration is a constant value is a directly proportional relationship. An example of this is the ideal gas law, PV = nRT. Pressure and volume are directly proportional to the number of molecules of an ideal gas present ad the temperature.

It may be called "the constant term".

Okay, so to figure out the relationship, derive it from the equation PV=nRT. In this, P is pressure, V is volume, n is the number of moles, r is the universal gas constant, and T is temperature. I recommend graphing pressure versus number of gas particles to see the relationship, but I would say it is probably a direct proportion. Hope this helped! :)
