\n" ); document.write( "\n" ); document.write( "What you ask cannot be done. You cannot write \"the\" equation of a line that contains a given set of points. That is because there are an infinite number of representations of such a line. The best you can do is write \"an\" equation of the desired line. Herewith the steps of procedure for writing an equation of a line through any two given points and .\r
