# Thread: Graphing this table of values

1. ## 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?

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?
