Question 564673
5x+y =	4				
Find the slope of this line 										
										
y=-5x+4				
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	(8,9)			
Find b by plugging the values of m & the point in										
y=mx+b										
9=8/5+b						
b=	37/5									
m=	 1/5									
The required equation is y= (1/ 5)x+37/ 5
