Question

i need help on math

Answer 1

Martai, do you need help with both of them?

Answer 2

uhhh he can't get banned for spamming a post, he can get banned for doing it like 100x times but not just the first few, at most he will get a warning

Answer 3

ok

Answer 4

I'll help you with your question.

The constant of proportionality is: `The ratio that relates two given values in what is known as a proportional relationship.` Remember it is your k value !!

There are two ways: Direct Variation and Inverse Variation.

Direct Variation: y = kx
Inverse Variation: y = k/x or k = y/x

Plugin your y and x values so you can find k.

Answer 5

Do you understand? Can you answer the questions?

Answer 6

no im just confused on the question

Answer 7

but i think ik half of the second part of the question

Answer 8

I just explained it to you...

Let me put it this way:

To find k (which is the constant of proportionality), the equation is:
\[k = \frac{ y }{ x }\]

Plug in any for your x and y values and solve.

Answer 9

ok i think ik now

Answer 10

alright, what did you get?

Answer 11

like for the second part

Answer 12

for this

Answer 13

oh ;/

Answer 14

yes

Answer 15

ok, then just apply what i just said to the table... do you want me to help you with that?

Answer 16

yes

Answer 17

ok, let's use the y-value 0.6 and the x-value 3


\[k = \frac{ y }{ x }\]
\[k = \frac{ 0.6 }{ 3 }\]

Solve for k.

Answer 18

oki

Answer 19

then u have y=1.3x

Answer 20

Did you solve for k?

Answer 21

yup

Answer 22

what did you get?

Answer 23

k=0.2

Answer 24

idk if thqts right

Answer 25

Correct, that means the constant of proportionality is 0.2

For the next question, we use the formula:
\[y = kx \]
\[y = 1.3x \]

What is the value of k?

Answer 26

Yes, thats correct!

Answer 27

so for thr first one is 0.2 and 1.3

Answer 28

Correct

Answer 29

Now for the coordinate plane, we do the same thing as the first time:

\[k = \frac{ y }{ x }\]

What point would you like to use as your x and y values?

Answer 30

wdym?

Answer 31

this... is that not the next question?

Answer 32

oh..

Answer 33

so this is not a question

Answer 34

Pick a point that passes through the line so that we can put it in the equation

Answer 35

x

Answer 36

Do you want me to pick a point for you?

Answer 37

yes

Answer 38

ok, lets do (2,5)

Remember:

(x,y) becomes (2,5)

\[k = \frac{ y }{ x }\]

Plugin your x and y values and solve.
