5/(0.2s+1)
I cant figure out how to give a value of 0.2 to the s term in the pole

Well, what are you trying to do ?
The two expressions above are equivalent. It may be easier to see in the second version that this tf has no zero and one pole at -5 rad/s.
So you can do for example :
[NUM,DEN] = zp2tf([],-5,1)
bode(NUM,DEN)
and actually see the roll off above the pole frequency.
