Answer:
Both lines are not parallel 
Step-by-step explanation:
Given as :
Two lines equation are as :
3y - 5x = 9   And  y = -  x - 12
x - 12
First line is now written in eq y = mx + c
Or,    3y = 5x + 9 
Or,      y =  x +
x +  
So, Slop of this line ( m 1 ) =  
      slop of second line ( m 2) is  
∵ The slop of both lines are not equal , so the line are not parallel to each other .
Hence Both lines are not parallel     Answer
