Question

The equations of two lines are x - 3y = 6 and y = 3x + 2. Determine if the lines are parallel, perpendicular or neither.

parallel
perpendicular
neither

Answer 1

@Xmoses1 I need your help!

Answer 2

Yes how can I help you?

Answer 3

Funny... You are the only one that seems willing to help.
There is something wrong with this picture though...

Answer 4

Well i sure wish that i had somebody other than myself to help me!

Answer 5

this blows...

Answer 6

do you have a graphing calculator

Answer 7

nevermind i don't think it is necessary

Answer 8

lol I like the guys names Xmoses1

Answer 9

no i dont do i need one?

Answer 10

solve both for "y" firstly, what do you get for each?

Answer 11

y = 3x + 2 (1)
x - 3y = 6
-3y = 6 - x
y = x/3 + 2 (2)

Parallel = same slope,
Perpendicular = negative recip.

It's neither of those, so neither.

Answer 12

When it is Parallel, the slopes are the same, and the y-intercept can be different.
When it is perpendiculator, the slopes are a negative reciprocal
if it is neither,the slopes are different

Answer 13

Ok thanks guys! Next time I will ask you guys for help rather than @Xmoses1. He was useless!
