If ideal gas law is obeyed...
density = mass/V == n/V
PV = nRT
P = (n/V)RT
If temp is held constant then increasing density increases pressure.

The other answers are right. But I am willing to offer an non- mathmatical answer for better understanding.
As the density is increased, more number of gas molecules [atoms for inert gases] collide on the conaining vessel wall. So the pressure increases. For reduced pressure density [increased volume] the opposit occurs. Then fewer molecules strike an unit area, so pressure decreases.
Thank you.

Pervert!
Er, Pv=nRT
Thus Pressure is linearly proportional to pressure.
