Question 426982
-7	x	+	9	y  	=	-2	
Find the slope of this line 							
							
9	y  	=	7	x	+	2	
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							
m1*m2=-1							
The slope of the required line will be 	-1.29	
m=	-1.29	,point	(-7,6)
Find b by plugging the values of m & the point in							
y=mx+b							
6=9+b			
b=-3						
m=-1.29						
The required equation is	y=-1.29	x-3
