Question 486291
x1		y1	x2	y2				
-2		4	3	4				
								
slope m =		(y2-y1)/(x2-x1)						
(	4	-	4	)/(	3	-	-2	) 
(	0	/	5	)  				
m=		0      						 
								
Plug value of  the slope  and point 			(	-2	,	4	) in	
Y 	=	m	x 	+	b			
4.00	=	-0    	+	b				
b=	4	-	-0    					
b=	4      							
So the equation  will be								
Y 	=	4
