Question 524746
1	x		-2	y  	=	5			
Find the slope of this line 									
									
-2	y  	=	-1	x	+	5			
Divide by 	-2								
	y  	=	1	x	+	-2.5			
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									
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 =-2 	x	+	9
