Answer: To determine if two lines are parallel or perpendicular, you have to look at the slopes. For the line y=kx+b, k is the slope.
For two lines y=k1x+b1 and y=k2X+b2 ,When K1=K2, two lines are parallel; when K1=-1/k2, two lines are perpendicular. It doesn't matter whatever b1, b2 are. Hence to save time, you only need to calculate k1 and k2.
To calculate the slope k of any line, you have to change the equation to y=kx+b
For -y=3x-2, k=3/(-1)=-3 (you divide -1 on each side of =, but you don't need to calculate -2/(-1))
For -6X+2y=6, K=6/2=3 (you first move the -6x to right side, it becomes 6x, then divide by 2)
Now you can get the answer: The two lines neither parallel nor perpendicular.
Answer: -204
Step-by-step explanation: 12 X -17 +Y is the same thing but you can say it this way and its easier to understand but it equals -204/(negative 204) Hope this helps you! :3

Answer:
life is a precious gift of GOD like see these days conditions too much people are dying life is our test it is worth whoever we wonder we are not birds,stones,mountains,trees they are also surviving and we are too we have not to survive we have to live our life there must be a difference between humans and animals i know life is brutal,tough and hard than why is it tough brutal and hard because it is a test a common life also passes and a man who serves hummanity his life also passes but a man serving hummanity is always remembered
