Question 557825
6	x	+	2	y  	=	-6				
Find the slope of this line 										
										
2	y  	=	-6    	x		-6				
Divide by 	2									
	y  	=	-3      	x	+	-3    				
Compare this equation with y=mx+b										
slope m =	-3    									
										
The slope of a line perpendicular to the above line will be the negative reciprocal										0.33
m1*m2=-1										
										
										
m=	 1/3	,point	(	4	,	-15	)			
Find b by plugging the values of m & the point in										
y=mx+b										
-15	=	4/3	+	b						
b=	-49/3									
m=	 1/3									
The required equation isy  	=	  1/ 3	x		-49/ 3
