Answer 15

ok

Answer 16

for the 12th month

Answer 17

good! so which answer choices have 36 cm

Answer 18

the correct answer is D

Answer 19

ok but what guarantees that?

Answer 20

just because you 36 does not guarantee it is correct

Answer 21

becuase we are trying to find the 12th month and 12*3 = 36 and D is the only one with 36

Answer 22

what if we had two answer choices that have 36 on them

Answer 23

yes in this case you are safe

Answer 24

then i would keep going and keep problem solving

Answer 25

but to confuse you i would have put 36 in more than one and you won't be sure anymore

Answer 26

ok

Answer 27

i'm not sure how to work that.

Answer 28

you have to find that model through the table

Answer 29

ok can you help me with that?

Answer 30

let's take the months as our x (input)
and height as our out put
ok

Answer 31

ok

Answer 32

y=3x as you said yourself according to table

Answer 33

ya

Answer 34

you give me an x i multiply by 3 to get y the height

Answer 35

so the kind of relation we have here is linear (direct relation)

Answer 36

ya

Answer 37

now what we do is go to options and see which exactly y=3x

Answer 38

in this case we know already it has to be y-9=3(x-3)

Answer 39

ya thats easy to find

Answer 40

if you solve that for y you get y=3x-9+9=3x which is the right one

Answer 41

the answer is still D

Answer 42

yes
