Question 729945
9      	x	+	7	y  	=	8				
Find the slope of this line										                                                                                                            
										
7	y  	=	-9      	x	+	8    				
Divide by	7									
	y  	=	-9/ 7	x	+	8/7				
Compare this equation with y=mx+b,					m= slope & b= y intercept					
slope m =	-9/7									
										
The slope of a line perpendicular to the above line will be the negative reciprocal										 7/9
Because m1*m2 =-1										
The slope of the required line will be			 7/9							
										
m=	 7/9	,point	(	6	,	-6	)			
Find b by plugging the values of m & the point in										
y=mx+b										
-6	=	14/ 3	+	b						
b=	-32/3									
m=	 7/9									
The required equation is y  	=	  7/ 9	x		-32/ 3
