<PRE><B>Question 546905</B>
x1		y1	x2	y2				
8		9	-9	-8				
								
slope m =		(y2-y1)/(x2-x1)						
(	-8	-	9	)/(	-9	-	8	) 
(	-17	/	-17	)  				
m=		1      						 
								
Plug value of  the slope  and point 			(	8	,	9	) in	
Y 	=	m	x 	+	b			
9.00	=	8    	+	b				
b=	9	-	-8    					
b=	17      							
So the equation  will be								
Y 	=	1    	x 	+	17    

x-y=-17
