The above table can be used for first Order any Order Pass filter 
Based on

f = 1 / 2π√(R1*C1*R2*C2)

if C1 = C2 and R1 = R2

f = 1 / 2πRC

Let's take an example of a Low Pass filter, let's say values are
R1 = 1000000 Ω
R2 = 1000000 Ω
C1 = 100000 pF
C2 = 100000 pF
Then cut-off frequency would be 15.92 Hz.

The roll-off behavior for high frequency would be
