Question 583548
x1		y1	x2	y2					
-7		-8	-3	-1					
									
slope m =(y2-y1)/(x2-x1)							
(	-1	-	-8	)/(	-3	-	-7	)	
(	7	/	4	)  					
m=		7/4						 	
The required line passes through both the points. So we select one point and plug it with the slope 									
Plug value of  the slope  and point (	-7	,	-8	) in		
Y	=	m	x	+	b				
-8.00	=	7/4	*	-7	+	b			
-8.00	=	-49/4	+	b					
b=	-8    	+	17/4						
b=	-12  1/ 4								
So the equation  will be									
Y 	=	7/4	x	+	17/4
