Question 539832
	y  	=	2      	x	+	12				
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	(	-2	,	4	)			
Find b by plugging the values of m & the point in										
y=mx+b										
4	=	1.00	+	b						
b=	3									
m=	- 1/2									
The required equation isy  	=-  1/ 2x	+	3
