Question 479911
x1		y1	x2	y2				
1		7	10	1				
								
slope m =		(y2-y1)/(x2-x1)						
(	1	-	7	)/(	10	-	1	) 
(	-6	/	9	)  				
m=		- 2/3		-  2/ 3				 
								
Plug value of  the slope  and point 			(	-1	,	8	) in	
Y 	=	m	x 	+	b			
8.00	=	 2/3	+	b				
b=	8	-	 2/3					
b=	7  1/ 3							
So the equation  will be								
Y 	=	- 2/3	x 	+	22/3
