Question 545797
x1		y1	x2	y2				
1		-2	-2	1				
								
slope m =		(y2-y1)/(x2-x1)						
(	1	-	-2	)/(	-2	-	1	) 
(	3	/	-3	)  				
m=		-  5/ 8						 
								
Plug value of  the slope  and point (	1,-2) in	
Y 	=	m	x 	+	b			
-2.00	=	- 5/8	+	b				
b=	-2	-	- 5/8					
b=	-11/ 8							
So the equation  will be								
Y 	=	- 5/8	x 		-11/8
