First we derive an expression for density of a gas. Density = mass(w)volume(V) but we know that PV = nRT now n = wM where M is molecular weight So, PV = wMRT this gives wV=PMRT = density = d clearly graph of pressure vs density is a straight line with slope = RTM steeper the line, more is the slope and so less is the mass (at a given temperature) so here M1>M2
