Question 548271
1	y  	=	3      	x		-7			
Divide by 	1								
	y  	=	3      	x	+	-7			
Compare this equation with y=mx+b,					m= slope & b= y intercept				
slope m =	3    								
									
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 	- 1/3						
									
m=	- 1/3	,point	(	-3	,	-4	)		
Find b by plugging the values of m & the point in									
y=mx+b									
-4=1.00+b					
b=-5								
m=	- 1/3								
The required equation is y=-  (1/3)x-5
