how to load a file into a mysql table for a particular column?
Manual states:
You can also discard an input value by assigning it to a user variable and not assigning the variable to a table column:

LOAD DATA INFILE 'file.txt'
  INTO TABLE t1
  (column1, @dummy, column2, @dummy, column3);


So in your case, it may look something like:

LOAD DATA INFILE '/path/point.txt' INTO TABLE tablename (@dummy, points);
