Question 592978
PARALLEL							
							
							
							
y  	=	-9    	x	+	7	
Divide by	1						
	y  	=	-9    	x	+	7    	
Compare this equation with y=mx+b							
slope m =	-9    						
The slope of a line parallel to the above line will be the same							
The slope of the required line will be	-9    				
m=	-9    	,point	(	-3	,	-5	)
Find b by plugging the values of m & the point in							
y=mx+b							
-5=27+b			
b=	-32						
m=	-9    						
Plug value of  the slope  and b	in y = mx +b		
The required equation isy=-9x-32      

PERPENDICULAR TO A LINE											

y  	=	-9      	x	+	7    					
Divide by	1										
	y  	=	-9      	x	+	7    					
Compare this equation with y=mx+b,					m= slope & b= y intercept						
slope m =	-9    										
											
The slope of a line perpendicular to the above line will be the negative reciprocal	 1/9	
m1*m2=-1											
The slope of the required line will be	 1/9								
											
m=	 1/9	,point	(	-3	,	-5	)				
Find b by plugging the values of m & the point in											
y=mx+b											
-5	=	-  1/ 3	+	b							
b=	-14/3										
m=	 1/9										
The required equation is y  	=	  1/ 9x-14/ 3
