Question 999154
x1		y1	x2	y2							
0		2	4	0							
											
slope m =		(y2-y1)/(x2-x1)									
(	0	-	2	)/(	4	-	0	)			
(	-2	/	4	)  							
m=		- 1/2						 			
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			(	0	,	2	) in				
Y	=	m	x	+	b						
2.00	=	- 1/2	*	0	+	b					
2.00	=	-0    	+	b							
b=	2    	+	0    								
b=	2      										
So the equation  will be											
Y 	=	- 1/2	x	+	2
