\n" ); document.write( "The y intercept is 4, which means the point (0,4) is on the graph. I'll label this as point A.
\n" ); document.write( "A = (0,4)
\n" ); document.write( "This is where the graph crosses the y axis.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "From point A, move down 3 units and to the right 5 units to arrive at point B = (5,1)
\n" ); document.write( "The movement \"down 3, to the right 5\" comes directly from the slope of -3/5
\n" ); document.write( "slope = rise/run
\n" ); document.write( "slope = -3/5
\n" ); document.write( "rise = -3 means we drop 3 vertical units (y axis)
\n" ); document.write( "run = 5 means we move to the right 5 units (x axis)
\n" ); document.write( "As the diagram below indicates, the red line goes downhill as you read from left to right. This downhill direction is because of the negative slope.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "After we have two points, we can draw a straight line through them
\n" ); document.write( "
\n" ); document.write( "I used GeoGebra to create the graph.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The equation of the red line in slope intercept form (y = mx+b) is \"y+=+expr%28-3%2F5%29x%2B4\"
\n" ); document.write( "m = -3/5 is the slope
\n" ); document.write( "b = 4 is the y intercept
\n" ); document.write( "
\n" ); document.write( "
\n" );
