Question 519511
x1		y1	x2	y2				
3		1	2	6				
								
slope m =		(y2-y1)/(x2-x1)						
(	6	-	1	)/(	2	-	3	) 
(	5	/	-1	)  				
m=		-5 

A Parallel line will have the same slope =-5     			
Plug value of  the slope  and point (	-4,0	) in
Y 	=	m	x 	+	b		
0.00	=	20    	+	b			
b=	0	-	20    				
b=	-20      						
So the equation  will be							
Y 	=	-5x-20
