Question 550374
PARALLEL

	y  	=	8/7	x	+	6		
Compare this equation with y=mx+b								
slope m =	8/7			0.8				
The slope of a line parallel to the above line will be the same								
The slope of the required line will be 8/7					
m=	8/7	,point	(	-2	,	2	)	
Find b by plugging the values of m & the point in								
y=mx+b								
2	=	-16/7	+	b				
b=	30/7
							
m=	8/7							
Plug value of  the slope  and b	in y = mx +b			
The required equation isy  	=	8/ 7	x	+	30/ 7	

PERPENDICULAR 

1	y  	=	8/7	x	+	6				
									
				
Compare this equation with y=mx+b										
slope m =	8/7									
										
The slope of a line perpendicular to the above line will be the negative reciprocal										-7/8
m1*m2=-1										
The slope of the required line will be 			-7/8				
										
m=	- 7/8	,point	(	-2	,	2	)			
Find b by plugging the values of m & the point in										
y=mx+b										
2	=	7/4	+	b						
b=	1/4									
m=	- 7/8									
The required equation is  y  	=	-  7/ 8	x	+	  1/ 4
