Question 856427
-5      	x	+	-4	y  	=	-29				
Find the slope of this line										                                                                                                            
										
-4	y  	=	5      	x		-29    				
Divide by	-4									
	y  	=	-5/ 4	x	+	29/4				
Compare this equation with y=mx+b,					m= slope & b= y intercept					
slope m =	-5/4									
										
The slope of a line perpendicular to the above line will be the negative reciprocal										 4/5
Because m1*m2 =-1										
The slope of the required line will be			 4/5							
										
m=	 4/5	,point	(	9	,	-4	)			
Find b by plugging the values of m & the point in										
y=mx+b										
-4	=	36/ 5	+	b						
b=	-56/5									
m=	 4/5									
The required equation is		y  	=	  4/ 5	x	-56/ 5
