Question

parallel , perpendicular or neither ????

Answer 1

I think its C (neither)

Answer 2

@Mateaus @Abbles @welshfella

Answer 3

did you graph both equations ?

Answer 4

yes i did ,

Answer 5

and either are parallel or perpendicular ..

Answer 6

so i think it is neither

Answer 7

Calculate the slope of both lines. Parallel lines have the same slope. Perpendicular lines have slopes that are the negative reciprocals of each other.

Answer 8

^

Answer 9

perpendicular means the angle between them is a right angle

Answer 10

well since are both will it be neither because they don't match?>>

Answer 11

Hint:
those lines are parallel, if m=m_1
are perpendicular if m*m_1=-1
where m, and m_1 are the correspondig slopes of your lines

Answer 12

i say Neither.

Answer 13

Yes! I think so!

Answer 14

Rather than graphing you should look at the slope of each line

the first equaiotn y= - x/4 +8

has a slope of -1/4

rearrange the SECOND equation until it is in the form
y=mx+ b

if the "m" value is -1/4 then they are parallel

if it is 4 then ythey are perpendicular

if neither , then neither

Answer 15

As stated earlier

Answer 16

@ospreytriple
Yes - I agree my post repeats yours.

Subsequent posts were full of 'graphs' ans 'I thinks' so I re-iterated the correct approach!

Answer 17

i asked abt graph
and yes it's good to check answer :-)

Answer 18

but you cannot definitively tell whether lines are perpendicular or parallel by looking a t a graph - they may be very close - but not exact and you could not see.

Answer 19

there is a huge difference between parallel and perpendicular lines we can easily find which one is it
2ndly i asked her did you graph it there is a reason for that and seems like she got the
answer by graphing
anyways rewrite in slope y-intercept is better than graphing .......
thanks :-)

Answer 20

my point is not that you can't tell the difference between parallel and perpendicular - that is obvious

but graph THESE 2 lines and tell me definitively are they parallel:

1000y = 999x+1

1000y =1001x -10000

My point is that you cannot tell whether the lines are exactly parallel by graphing
These 2 are NOT
