Graph Question...

Answer 1

The location of an ant from a tree was 3 meters west (negative direction). The ant walked towards the tree at a constant rate and reached the tree in 2 minutes. If y represents the location of the ant from the tree, in meters, and x represents the time in minutes, which graph best represents this situation?

Answer 2

Im thinking either C or d because it says negative direction

Answer 3

We could both agree that all of them are a negative slope, correct?

Answer 4

NOw, what does y, and x represent?

Answer 5

no the first 2 have a postive right?

Answer 6

Lol, yes sorry. So, we eliminate that.

Answer 7

Ok

Answer 8

Now, what does y and x represent?

Answer 9

y = location of the ant from the tree

Answer 10

Yes, which is what number?

Answer 11

2

Answer 15

Then what number is it?

Answer 16

minutes

Answer 17

Awesome!

Answer 18

lol now what

Answer 19

We both know the x and y values.

Which graph shows that the line is touching y3?

Answer 20

Wait, hold on.

Answer 21

well. obviously you can eliminate A and D because they have x-coordinates that are negative

time cant really be negative

Answer 22

Hmm. I'm thinking B. Because the line is touching y3.

Answer 23

thats true

Answer 24

but B is positive...

Answer 25

B is corect

Answer 26

Crap I meant negative 3.

Answer 27

I'm confused about the signs though. @nikato

Answer 28

becaause you're starting time would be 0 seconds and the ant is 3 m west of the tree so (-3)

Answer 29

So, B was correct?

Answer 30

Ohhhh ok i get it now

Answer 31

and B is the only graph that contains (0,-3)

Answer 32

@camerondoherty, sorry about that confusion.

Also, @nikato, thanks for clearing that up!

Answer 33

Thank You Guys

Answer 34

C would be wrong because it shows the ant's starting location as 2 m east of the tree, which isnt what you want

Answer 35

and Since we eliminated A and D and now C it would be D

Answer 36

i mean B

Answer 37

lol

Answer 38

yea.pretty much
