slope m = y1-y2 over x1-x2
\n" ); document.write( "in words divide the difference in y by the difference in x
\n" ); document.write( "This is sometimes called rise over run where y is the rise and x is the run.
\n" ); document.write( "the two y's are 2 and -7
\n" ); document.write( "the two x's are 7 and 9
\n" ); document.write( "Don't forget change of signs when subtracting\r
