Question 740302
1    	x	+	2	y  	=	3	
Find the slope of this line							
make y the subject							
2	y  	=	-1    	x	+	3	
Divide by	2						
	y  	=	- 1/2	x	+	1 1/2	
Compare this equation with y=mx+b							
slope m =	- 1/2						
The slope of a line parallel to the above line will be the same							
The slope of the required line will be			- 1/2				
m=	- 1/2	,point	(	-1      	,	1	)
Find b by plugging the values of m & the point in							
y=mx+b							
1	=	  1/ 2	+	b			
b=	0.5						
m=	- 1/2						
Plug value of  the slope  and b					in y = mx +b		
The required equation is		y  	=	- 1/2	x	+	  1/ 2
