Question 639367
2      	x	+	7	y  	=	-49					
Find the slope of this line											
											
7	y  	=	-2      	x		-49    					
Divide by	7										
	y  	=	-  2/ 7	x		-7    					
Compare this equation with y=mx+b,					m= slope & b= y intercept						
slope m =	- 2/7										
											
The slope of a line perpendicular to the above line will be the negative reciprocal										7/2	
Because m1*m2 =-1											
The slope of the required line will be	7/2								
											
m=	7/2	,point	(	7	,	-9	)				
Find b by plugging the values of m & the point in											
y=mx+b											
-9	=	49/ 2	+	b							
b=	-67/2										
m=	7/2										
The required equation isy  	=	(7/2)x-67/ 2
