James / Katie,
7speed, you will need a hanger bracket, as from your picture, the Shimano is hangerless, meaning it fits directley too the frame to combate this, you can buy a bracket, but bear in mind, if your using trist grip of non shimano, just google the ration of your current twist, dont worry they are easy to fit, also as a tip, once you have fit the derilleur, to avoid splitting the chain, remove the rear derailleur allen key cog, chase the chianaround the new derailleur, refit the cog, good luck

Nope, the pull ratio would be wrong and the chain too wide for the cage.
This is not a recommended fitment, as the 9 speed derailleur is too narrow for the 7speed chain. Ideally, you will need a 7/8 speed derailleur.
