Question 566450
1	y  	=	4    	x		-2			
Divide by 	1								
	y  	=	4      	x	+	-2    			
Compare this equation with y=mx+b									
slope m =	4    								
									
The slope of a line perpendicular to the above line will be the negative reciprocal									
m1*m2=-1									
									
									
m=	- 1/4	,point	(	4	,	2	)		
Find b by plugging the values of m & the point in									
y=mx+b									
2=-1  +	b					
b=	3      								
m=	- 1/4								
The required equation is y=- ( 1/ 4)x+3
