\n" ); document.write( "it's a lower case m.
\n" ); document.write( "It is the \"steepness\" of the line in the graph. Level, or horizontal, is a slope of zero. It's parallel to the x-axis, and \"flat.\"
\n" ); document.write( "The slope, m, is the change in y divided by the change in x.
\n" ); document.write( "For those 2 points, it's

\n" ); document.write( "--------
\n" ); document.write( "It's positive, so it increases to the right. y increases 2 for each x increase of 1.
