Question 568170
3	x	+	1	y  	=	4	
Find the slope of this line 							
	y  	=	-3      	x	+	4    	
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							
m1*m2=-1							
						
m=	 1/3	,point	(	5	,	9	)
Find b by plugging the values of m & the point in							
y=mx+b							
9	=	1/ 3*5	+	b			
b=	22/ 3						
m=	 1/3						
The required equation is y =	  1/ 3	x	+	22/ 3
