the two lines y=2/5x+9 and y= -2/5x-9 are: 
a) parallel 
b) perpendicular 
c)neither
                                             
                                          
                                          
                                        
											 
											Answer:
neither
Step-by-step explanation:
parallel lines have the same slope and different y-intercept
perpendicular lines have the reciprocal as slopes( 2/5 and 5/2)
as these slopes have neither the answer in NEITHER
