Question 501497
-0.2	x	+	1	y  	=	7				
Find the slope of this line 										
										
1	y  	=	0.2	x	+	7				
Divide by 	1									
	y  	=	0.200	x	+	7				
Compare this equation with y=mx+b										
slope m =	0.20									
										
The slope of a line perpendicular to the above line will be the negative reciprocal										-5
m1*m2=-1										
The slope of the required line will be 			-5.00							
										
m=	-5    	,point	(	4	,	-3	)			
Find b by plugging the values of m & the point in										
y=mx+b										
-3	=	-20.00	+	b						
b=	17									
m=	-5    									
The required equation is y  	=	-5      	x	+	17
