Martai, do you need help with both of them?

axie:

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

he will be banned once the mods deem him incapable of following the rules to the site

martai:

ok

yes i do

carmelle:

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. Here is a useful website where you can learn more: https://www.cuemath.com/commercial-math/constant-of-proportionality/

ok thx

carmelle:

Do you understand? Can you answer the questions?

martai:

no im just confused on the question

martai:

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

carmelle:

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.

martai:

ok i think ik now

carmelle:

alright, what did you get?

martai:

like for the second part

martai:

for this

do you understand this?? ^

martai:

yes

carmelle:

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

martai:

yes

carmelle:

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.

martai:

oki

martai:

then u have y=1.3x

carmelle:

Did you solve for k?

martai:

yup

carmelle:

what did you get?

martai:

k=0.2

martai:

idk if thqts right

carmelle:

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?

i got 1.3 :/

carmelle:

Yes, thats correct!

martai:

so for thr first one is 0.2 and 1.3

carmelle:

Correct

carmelle:

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?

martai:

wdym?

carmelle:

this... is that not the next question?

martai:

oh..

martai:

so this is not a question

carmelle:

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

martai:

x

carmelle:

Do you want me to pick a point for you?

martai:

yes

carmelle:

ok, lets do (2,5) Remember: (x,y) becomes (2,5) \[k = \frac{ y }{ x }\] Plugin your x and y values and solve.
