Pressure in liquid change linearly with depth. 
The pressure at depth 'd' in a liquid of density 'ρ' is:

P = \rho gd

where
P = pressure
ρ = density of liquid
g = acceleration due to gravity
d = depth

Hydrostatic Pressure in a  liquid is the pressure at a point in liquid when the liquid is not flowing.

Hydrostatic pressure at a point at a depth of h, from the surface of liquid of density ρ at a location with gravity g    =    P2 =  ρ g  h  +  P1
     where P1 = pressure of the gas or air above the surface of the liquid

The excess pressure due to the depth in a liquid varies as    ρ g h.

This pressure is due to the weight of the column of liquid above the point under consideration.    P2 - P1 =  mass * g / Area =  ρ (A h) * g / A  = ρ g h
