In a business letter, the salutation comes after the reference. Typically, the reference is included in the header or body of the letter, often as a reference line or subject line, and serves to indicate the purpose or context of the correspondence. The salutation follows, addressing the recipient directly, such as "Dear [Recipient's Name]."
A reference line is a line that is perpendicular to the surface at the point of incidence. It is used as a point of reference for measuring the angles of incidence and reflection relative to the surface. The angle of incidence is measured between the incident ray and the reference line, while the angle of reflection is measured between the reflected ray and the reference line.
No, a reference line on a business letter is optional. The reference line is used when a specific piece of information is the subject of the letter, such as a contract, an account or invoice number, a particular product or service, etc. The reference line makes it easy for the recipient to find that piece of information for follow up without having to search through the letter to find it. A thank you letter or a general information or request letter does not require a reference line; the purpose of the letter is stated in the first sentence of the first paragraph of the letter.

A reference line is a vertical or horizontal line in a graph, corresponding with user-defined values on the x-axis and y-axis respectively. Reference lines further aid the determination of angular and linear measurements.
