What is the mathematical relationship between pressure, p, and intensity, I ?

No relationship. Intensity can be any value so is the pressure. Pressure and intensity are not related.

I = watt/m^2
p = N/m^2
since watt are N*m/sec , then I/p = m/sec , i.e. a speed

The ENERGY stored in something that is compressed, like a spring, is proportional to the square of the compression.
( E =1/2 k x^2 = 1/2 k (yP)^2)
so that the intensity ( meaning the energy in the wave ) is proportional to the square of the physical amplitude.
Which in turn is a measure of the pressure.
so i is proportional to P^2
