Your question is ambiguous.

Assuming you have a current buffer and a variable bound to a string,
if you want to replace the line where the point is currently with the
contents of your string, you could do:

    (delete-region (progn (beginning-of-line) (point))
                   (progn (end-of-line) (point)))
    (insert string)

For example, to change the first line of the *scratch* buffer, you could
evaluate:

(let ((string ";; This is a new line for a lisp buffer."))
  (with-current-buffer "*scratch*"
    (goto-line 1)
    (delete-region (progn (beginning-of-line) (point))
                   (progn (end-of-line) (point)))
    (insert string)))
