Question 572898
8x	+y  	=	-19					
Find the slope of this line											
											
y  =	-8x-19					
Compare this equation with y=mx+b,	m= slope , & b= y intercept						
slope m =	-8    										
											
The slope of a line perpendicular to the above line will be the negative reciprocal										 1/8	
m1*m2=-1											
The slope of the required line will be	 1/8				
m=	 1/8	,point	(	-9	,	7	)				
Find b by plugging the values of m & the point in											
y=mx+b											
7	=	-9/ 8	+	b							
b=	-65/8									
m=	 1/8										
The required equation is y =  1/ 8x-65/ 8
