Slow performance after installing Yosemite on an older Mac is often caused by inadequate memory. Although you can install the upgrade on a Mac with 2 GB of memory, experience has shown that at least 4 GB is needed for full performance.

Select About This Mac from the Apple menu. If you have less than 4 GB of memory, and your model has upgradable memory, install as much as it can take, or at least that much. Any reputable RAM vendor will have a web form in which you can select the Mac model and be directed to compatible parts.

Memory in the MacBook Air is not upgradable. If that's what you have, you should restore the previous system from a backup, or replace the machine. Ask if you need guidance.

Do a backup, preferably 2 separate ones on 2 separate drives.

Revert to a Previous OS X - Yosemite

Revert Yosemite to Mavericks

If you do revert, I'd use Setup Assistant to restore your data. This process takes a while, so do it when you won't need the computer for several hours, based on my experience.
