how do you mark the syllables, separate the feet with vertical lines, and indicate the rhyme scheme of the following passages

That time of year thou mayst in me behold______

When yellow leaves, or none, or few, do hang_____

Upon those boughs which shake against the cold,________

Bare ruined choirs where late the sweet birds sang._______

This webpage shows how I've seen it done most of the time. For the lines you've given, you'll be using iambic pentameter.

*/ | */ | */ | */ | */
That time | of year | thou mayst | in me | behold

I used bold to indicate the stressed syllables (/) and left the unstressed syllables (*) unbolded.
Rhyme scheme is indicated by letters. The rhyme scheme for these four lines is indicated like this:

ABAB

or

A
B
A
B
