y=2x+3 (red line).
\n" ); document.write( "y intercept=3
\n" ); document.write( "(4,2) with slope=-1
\n" ); document.write( "2=-1*4+b
\n" ); document.write( "2=-4+b
\n" ); document.write( "b=2+4
\n" ); document.write( "b=6 the y intercept.
\n" ); document.write( "y=-x+6 (green line).
\n" ); document.write( "y intercept=6
\n" ); document.write( "6-3=3 answer between these 2 iy intercepts.
