Is it possible to git-checkout a single line instead of the entire file?

If I have modified several lines of a versioned file, is it possible to undo the changes of a line by command-line?

Just like I would do for an entire file with:

git checkout /path/to/file.extension

but doing something like, say

git checkout /path/to/file.extension --line 10

is this possible?

To elaborate on Matt's answer, git checkout --patch -- <path argument> starts an interactive mode with the following options: 

y - stage this hunk
n - do not stage this hunk

q - quit; do not stage this hunk or any of the remaining ones
a - stage this hunk and all later hunks in the file
d - do not stage this hunk or any of the later hunks in the file
g - select a hunk to go to
/ - search for a hunk matching the given regex
j - leave this hunk undecided, see next undecided hunk
J - leave this hunk undecided, see next hunk
k - leave this hunk undecided, see previous undecided hunk
K - leave this hunk undecided, see previous hunk

s - split the current hunk into smaller hunks
e - manually edit the current hunk

? - print help

The y n s and e options are a good place to start.

You can use git checkout -p to see each hunk individually and decide whether to check them out or leave them as is (and that takes an optional path argument as well if you'd like to narrow it down further).
