Rails: How to determine where a helper methods 'points'

Question

Near the start of this page...

http://guides.rubyonrails.org/routing.html

... there's an example involving @patient (section 1.2).

I'd like to know how to determine where the following line points:

<%= link_to 'Patient Record', patient_path(@patient) %>

What about the list generated by rake routes correlates to this?
How do I know which http verb is used?

EDIT

I'd like to add that pointing me to 'rake routes' will not explain it for me. I have checked my list of routes many times.

I'd like to know how, in the example on the URL above, I would know where the link_to line points. It seems like the list of routes is significant, but HOW does it correlate with the patient_path line? What am I missing?

This should give you the answer:

bundle exec rake routes | grep patient

About HTTP verb, url helpers only determine path/url, they don't determine HTTP method.

Well, before I type 'bundle exec' into my command prompt would you mind telling me what that does? Thanks. – moosefetcher Dec 09 '14 at 11:25
I've read the page and I still don't know what it will do. Any advice at all? – moosefetcher Dec 09 '14 at 11:37
It will 'Execute a command in the context of the bundle', with all gems in appropriate versions required. – Marek Lipka Dec 09 '14 at 11:38
Error: 'grep is not recognized as an internal or external command...'. What am I trying to find out here? Will it let me know how the example on that page works? – moosefetcher Dec 09 '14 at 11:41
I thought you're running on linux. So run `bundle exec rake routes` and seach for `patient` route manually. – Marek Lipka Dec 09 '14 at 11:42
