Question 516064
1	x	+	2	y  	=	7	
Find the slope of this line 							
make y the subject							
2	y  	=	-1	x	+	7	
Divide by 	2						
	y  	=	-0.5	x	+	3.5	
Compare this equation with y=mx+b							
slope m =	-0.5			-0.5			
The slope of a line parallel to the above line will be the same							
The slope of the required line will be 			-0.5				
m=	-0.5	,point	(	8	,	9	)
Find b by plugging the values of m & the point in							
y=mx+b							
9	=	-4.00	+	b			
b=	13						
m=	-0.5						
Plug value of  the slope  and b in y = mx +b		
The required equation isy  	=	-0.5	x	+	13
		y  	=	-  1/ 2	x	+	13
