\n" );
document.write( "Slope -2 Or -2/1 tells us as x increases by one, y decreases by 2 Or that
\n" );
document.write( "as x decreases by one, y increases by 2
\n" );
document.write( "( 4, 4)
\n" );
document.write( "(-3, y)
\n" );
document.write( "Here, x has decreased by 7, therefore y must increase by 14 so as to satisfy the slope conditions (14/-7) = - 2/1
\n" );
document.write( "(-3, 18) is a point on this line
\n" );
document.write( "y = 18\r
\n" );
document.write( "\n" );
document.write( "y = mx + b  (y =-2x + b   4 = -2*4 + b   b =12)

document.write( "y= -2x + 12
