From ideal gas equation, P V=\mu R T

\therefore P=\frac{\mu R}{V} T

Comparing this equation with y=m x slope of line \tan \theta=m=\frac{\mu R}{v} i.e. v \alpha \frac{1}{\tan \theta}

It means a line of smaller slope represents a greater volume of  gas, For the given problem figure,

Point 1 and 2 are on the same line so they will represent the same volume i.e. v_{1}=v_{2}

Similarly,

point 3 and 4 are on the same line so they will represent the same volume ie v_{3}=v_{4}
