I've had problems with a low drain when I bought the house, and have since tried chemicals, and had it augered out. Previous plumber said pipe was dry. I opened the wall behind the bathroom thinking maybe pipe was angled back toward the sink. It look like the right slope away from the sink. This is a pic of the sink drain to stack. What can be the problem if it's not clogged???

After that short horiz section of drain pipe connects to the tee on the right the clog could be after that point, right? How far down the drain line (feet) did the plumber clean/snake/auger? Did you remove and clean the trap directly under the bathroom sink? Does the bathtub/shower in that same room drain ok?

Those old style durham and galvanized systems are notorious for rusting out, particularly if there is a short galvanized nipple involved. The rust will clog the opening to the point that over time crud builds up inside the pipe and fittings. Replace these systems after they get so old as the rust will create a hole/leak. ABS is your friend.

Galvanized piping is notorious for slow drainage. Over time the inside of the pipe will get rough, which translates into blockages. Since the pipe walls get rougher with age, the pipe walls tend to grab hair and anything else you can imagine. I have had to cut out numerous sections of galvanized piping for this same reason. Most of the time I simply replace the galvanized piping with PVC.
However, that may not be your problem. If your bathroom sink has a pop-up drain please remove and inspect it. Often times hair gets caught up in the pop up assembly. After you remove the pop up assembly check the riser pipe between the pop-up drain and the P-trap. The riser pipe will often times have an accumulation of toothpaste and hair.
You may have a partial blockage downstream of the sanitary tee. See if you can snake through the galvanized piping and down into your fixture branch. You may not be able to get past the short turn galvanized elbow. I would only use chemicals as an absolute last resort.
The last thing that I would check would be the vent line directly above the sanitary tee where the galvanized piping connects. If your vent has become blocked this could cause your sink to drain slowly. Can you see if you can snake it from the roof?
