Question 443624
9	y  	=	7	x	+	2		0.75		
Divide by 	9									
	y  	=	 7/9	x		0.22				
Compare this equation with y=mx+b										
slope m =	0.78									
										
The slope of a line perpendicular to the above line will be the negative reciprocal										-1.29
m1*m2=-1										
The slope of the required line will be 			-1.29		
-1.29=-1.29		
										
m=	-1.29	,point	(-7,6)			
Find b by plugging the values of m & the point in										
y=mx+b										
6=9.00+	b						
b=	-3									
m=	-1.29									
The required equation is y=-1.29x-3
