Question 535540
x1		y1	x2	y2				
-1	*	-2	-3	-7				
								
slope m =		(y2-y1)/(x2-x1)						
(	-7	-	-2	)/(	-3	-	-1	) 
(	-5	/	-2	)  				
m=		5/ 2						 
								
Plug value of  the slope  and point (	-1,-2) in	
Y 	=	m	x 	+	b			
-2.00	=	-5/2	+	b				
b=	-2	-	5/2					
b=	-9/ 2							
So the equation  will be								
Y 	=	5/2	x 		-9/2
