Question 1026989
1      	x	+	-5	y  	=	4				
Find the slope of this line										                                                                                                            
										
-5	y  	=	-1      	x	+	4    				
Divide by	-5									
	y  	=	  1/ 5	x	+	- 4/5				
Compare this equation with y=mx+b,					m= slope & b= y intercept					
slope m =	 1/5									
										
The slope of a line perpendicular to the above line will be the negative reciprocal										-5    
Because m1*m2 =-1										
The slope of the required line will be			-5    							
										
m=	-5    	,point	(	0	,	-5	)			
Find b by plugging the values of m & the point in										
y=mx+b										
-5	=	-0      	+	b						
b=	-5    									
m=	-5    									
The required equation is		y  	=	-5      	x		-5
