The [SRUX doc](https://khanacademy.atlassian.net/wiki/spaces/LC/pages/3460366348/Linear) still needs a label for the grab handle, but I tried my best in the meantime. - Add a label and describedby for the grab handle. - Add aria-live states for the different interactive elements so they don't override each other. Issue: https://khanacademy.atlassian.net/browse/LEMS-1726 Test plan: `yarn jest packages/perseus/src/widgets/interactive-graphs/graphs/linear.test.tsx` Storybook - http://localhost:6006/iframe.html?id=perseuseditor-widgets-interactive-graph--interactive-graph-linear&viewMode=story - Try all the different slopes and intercepts - Move different elements and confirm that the updated aria-label is what is read out, and none of the other elements override the currently focused one.

This might've changed since you looked at it last, but the copy is different in the SRUX doc
