How are the vertex coordinates of a 3d patch defined? Is it possible to scale a patch by having vertrices and face information?

I have a 3d patch and its vertex coordinates are like:

        -0.6660         0    2.3060
        -1.6440         0    3.7400
        -0.6660    1.6000    2.3060
        -1.5050    9.6000    3.5140
        -0.4700    9.6000    2.0550
        -2.3700    9.6000    5.0800
        -2.4610         0    5.2710
        -3.0550    9.6000    6.7320
        -3.1070         0    6.8820
        -3.5500    9.6000    8.4510
        ...

I do not understand. How the coordinates could be numbers like -3.0550 or 6.732? How are these coordinates defined?

And is it possible to scale this patch to a smaller size having this coordinates and the "face" vector?
