    Graphing this table of values

    X::Y
    20::25.6
    40::6.4
    60::2.6
    80::1.8
    100::1.2

    How do I graph that and write a relation between Y and X?

    I can see an approximate pattern here.

    \frac{f(20)}{4}\approx{f(40)}

    \frac{f(40)}{3}\approx{f(60)}

    I'm not sure what it means, but maybe I've helped. Don't you have a graphing utility with regression capabilities?
