Question 549615
x1		y1	x2	y2				
2		-2	-1	10				
								
slope m =		(y2-y1)/(x2-x1)						
(10-	-2)/(-1	-2) 
(	12	/	-3	)  				
m=		-4      						 
								
Plug value of  the slope  and point 			(	2	,	-2	) in	
Y 	=	m	x 	+	b			
-2.00	=	-8    	+	b				
b=	-2	-	8    					
b=	-10      							
So the equation  will be								
Y 	=	-4    	x 		-10
