Watch the Combine The 6th And 9th online guitar lesson by Rob Garland from The Guitarist's Pentathlon

A breakdown of my lick shows how I let the 9th (A) sustain against the Gm7 chord and then I resolved the 6th (E) by giving it a half step bend to F. Experiment creating lines that move between the 6th and 9th, make these new notes part of your sound.
