The slope is given as <IMG STYLE=\"max-width:80%;\" SRC=/cgi-bin/plot-formula.mpl?expression=DELTA%28y%29%2FDELTA%28x%29 ALIGN=MIDDLE  ALT=\"DELTA%28y%29%2FDELTA%28x%29\"   DISABLED_style= \"max-width:90%; height:auto;\" > where the Greek letter delta represents the change (change in y over change in x). For a linear function in the form y = mx + b, m is the slope. For non-linear functions there is an operator called the \"derivative\" which essentially measures the slope of two points on a curve that are infinitely close together. </SPAN>\n" );
