Question 535935
	y  	=	0.50	x	+	4				
Compare this equation with y=mx+b										
slope m =	 1/2									
										
The slope of a line perpendicular to the above line will be the negative reciprocal 
m1*m2=-1										
The slope of the required line will be 	-2    							
										
m=	-2    	,point	(	3	,	2	)			
Find b by plugging the values of m & the point in										
y=mx+b										
2	=	-6	+	b						
b=	8									
m=	-2    									
The required equation is y  =	-2x+8
