One way to put a Prime graph in a Word document is via the Connectivity Kit:
1. Run the Connectivity Kit and connect your Prime via USB cable (or run the emulator).
2. Right-click the name of your calculator in the Connectivity Kit's left column.
3. Select "Get screen capture".
4. If necessary, click the "Refresh" button in the Screen Capture window, to capture Prime's current screen.
5. Click the "Copy" button in the Screen Capture window. This copies the image to the Windows clipboard.
6. Paste the image directly into Word (e.g. by pressing CTRL-V in Word).
Of course, you can optionally paste the screen capture from the clipboard into your favorite "paint" program, and then save it as an image file, so that you'll have it available for any use at any time.
Hope that helps!
