Question 536890
1	x		-2	y  	=	3				
Find the slope of this line 										
										
-2	y  	=	-1	x	+	3				
Divide by 	-2									
	y  	=	0.50	x	+	-1.5				
Compare this equation with y=mx+b										
slope m =	 1/2									
										
The slope of a line perpendicular to the above line will be the negative reciprocal										-2
m1*m2=-1										
The slope of the required line will be 			-2    							
										
m=	-2    	,point	(	-2	,	-5	)			
Find b by plugging the values of m & the point in										
y=mx+b										
-5	=	4.00	+	b						
b=	-9									
m=	-2    									
The required equation is y  	=-2x-9
