Question 546420
1	y  	=	-2      	x	+	6				
Divide by 	1									
	y  	=	-2      	x	+	6				
Compare this equation with y=mx+b,					m= slope & b= y intercept					
slope m =	-2    									
										
The slope of a line perpendicular to the above line will be the negative reciprocal										0.5
m1*m2=-1										
The slope of the required line will be 			 1/2							
										
m=	 1/2	,point	(	-4	,	8	)			
Find b by plugging the values of m & the point in										
y=mx+b										
8	=	-2.00	+	b						
b=	10									
m=	 1/2									
The required equation is , y  	=  1/ 2	x	+	10 
multiply by 2
2y=x+20 
-x+2y=20
