Question 570844
1	y  	=	5    	x		-3	
Divide by 	1						
	y  	=	5      	x		-3	
Compare this equation with y=mx+b							
slope m =	5      						
							
The slope of a line perpendicular to the above line will be the negative reciprocal	- 1/5						
m1*m2=-1							
							
							
m=	- 1/5	,point	(	2	,	1	)
Find b by plugging the values of m & the point in							
y=mx+b							
1	=	-2/5	+	b			
b=	7/5						
m=	- 1/5						
The required equation is y  	=	-  1/ 5	x	+	7/ 5
