What is true of it
F9 is F, A, C, E♭ and G — 1, 3, 5, b7 and 9 counted from F.
On an instrument that cannot reach all 5, the 5 and 1 go first, in that order.
The easiest of the 5 fingerings below is 101011: 4 fingers, held at the 1st fret.
2 of them use open strings, which is what makes a shape quiet to change to.
Where its notes are on the neck
The brass dots are F, the root. Everything else is a chord tone with its degree printed in it.

An inversion is the same chord with a different note lowest. The name changes to a slash name because the bass is what a listener hears as the foundation.
