Let the point A be (3, 5)
\n" ); document.write( "and point B be (9, 6)\r
\n" ); document.write( "\n" ); document.write( "The slope of the line is given by \r
\n" ); document.write( "\n" ); document.write( " \"=+%286-5%29%2F%289-3%29\"
\n" ); document.write( " \"=+1%2F6\"\r
\n" ); document.write( "\n" ); document.write( "The equation of a straght line is given by\r
\n" ); document.write( "\n" ); document.write( "y = mx + c where m is the slope.\r
\n" ); document.write( "\n" ); document.write( "Thus the equation becomes\r
\n" ); document.write( "\n" ); document.write( "\"y+=+%281%2F6%29x+%2B+c\"\r
\n" ); document.write( "\n" ); document.write( "Lets put x = 3 and y = 5 in the above equation.\r
\n" ); document.write( "\n" ); document.write( " \"5+=+%281%2F6%293+%2B+c\"
\n" ); document.write( " \"5+=+1%2F2+%2B+c\"
\n" ); document.write( " \"+c+=+9%2F2\"\r
\n" ); document.write( "\n" ); document.write( "Thus he equation of the straight line joining the two points is given by\r
\n" ); document.write( "\n" ); document.write( "\"y+=+%281%2F6%29x+%2B+%289%2F2%29\"
\n" ); document.write( "
\n" );
