Question 583508
2      	x	+	-9	y  	=	-1				
Find the slope of this line										
										
-9	y  	=	-2      	x		-1    				
Divide by	-9									
	y  	=	  2/ 9	x	+	 1/9				
Compare this equation with y=mx+b,					m= slope & b= y intercept					
slope m =	 2/9									
										
The slope of a line perpendicular to the above line will be the negative reciprocal = -9/2
m1*m2=-1																	
m=	-9/2	,point	(-2,3)			
Find b by plugging the values of m & the point in										
y=mx+b										
3	=	9      	+	b						
b=	-6    									
m=	-9/2									
The required equation is y  =	-9/ 2	x-6
