One method is to enter some more data on the worksheet for defining the new
line. Then use Chart | Source Data | Series | Add ...

Another method is to use Add Trendline (but you seem to want a horizontal
line, not necessarily a best-fit line).

You did not specify what type of chart you have (Line, XY(Scatter), ...), so
it is difficult to provide more detailed instructions.
