What is the use of dashed line?

A dash is a little horizontal line that floats in the middle of a line of text (not at the bottom: that's an underscore). It's longer than a hyphen and is commonly used to indicate a range or a pause. Dashes are used to separate groups of words, not to separate parts of words like a hyphen does.
