Question

I have to read a play and i need to properly state cerain lines like act scene and line number?
“I have a widow aunt, a dowager Of great revenue, and she hath no child: From THENS IS HER house, remote seven leagues; And she respects me as her only son”. I.i 157-160 is this correct format
it is act 1 scene 1 and line 157-160
but what if the act was 2 and scene 2 , how do i write that and the line was 123-134
