I'LL TRY TO EXPLAIN THE SLOPE.
\n" ); document.write( "IN THE LINE FORMULA [Y=mX+b] THE m VALUE IS THE SLOPE.
\n" ); document.write( "WE CALCULATE THE SLOPE FROM 2 SETS OF POINTS.
\n" ); document.write( "AN EXAMPLE IS:
\n" ); document.write( "(2,4) (4,9)
\n" ); document.write( "THE FORMULA IS:
\n" ); document.write( "(Y2-Y1)/(X2-X1)
\n" ); document.write( "(9-4)/(4-2)
\n" ); document.write( "5/2 OR 2.5 IS THIS SLOPE.
\n" ); document.write( "The numerator indicates how many units change in the y direction.
\n" ); document.write( "The denominator indicates how many units change in the x direction.
\n" ); document.write( "THIS VALUE IS THE INCLINATION OF A LINE.
\n" ); document.write( "A PLUS SLOPE IS A LINE THAT GOES FROM THE BOTTOM LEFT TO THE TOP RIGHT.
\n" ); document.write( "A NEGATIVE SLOPE GOES FROM LOWER RIGHT TO THE TOP LEFT.
\n" ); document.write( "2 EXAMPLES ARE SHOW ON THE FOLLOWING GRAPH.
\n" ); document.write( "THE RED LINE HAS A POSITIVE SLOPE WHILE THE GREEN LINE HAS A NEGATIVE SLOPE.
\n" ); document.write( "Y=4X+6 (RED LINE)
\n" ); document.write( "Y=-5X-4 (GREEN LINE)
\n" ); document.write( " $\"+graph%28+300%2C+200%2C+-6%2C+5%2C+-10%2C+10%2C+4x+%2B6%2C+-5x+-4%29+\"$ (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions 4x +6 and -5x -4). \n" ); document.write( "
