It is at constant temperature, a consequence of Boyle's law.

Explanation:

The ideal gas equation states #pV = nRT# where p is pressure, V is volume, n is amount of substance (no. of moles), R is gas constant and T is temperature.

If temperature remains constant, then because the amount of substance is constant, and the gas constant is, of course, constant, then it means that #nRT# is constant (#pV =# constant is Boyle's law).

So if #pV =# a constant, it means that a plot of pV against p is a straight line which is parallel to the x axis.
