Alright, @Ms-Brains I don't know the formulas or whatever, but I've found it is quite easy to make up your way through math

Answer 3

alright, so you wanna help?

Answer 4

Yea, I think I might be able to

Answer 5

Alright, so I'm using the graphing calculator Desmos, so I might be incorrect.

Answer 6

Now, if you try graphing the letter x, then it looks like this

Answer 7

Answer 8

@Ms-Brains If you look at that, you will see that the y-intercept is 0, and the slope is always 1.

Answer 9

Hmm... i don't really understand how this happened, but the green shading looks like this, when you add he +3y and the <= 6 part

Answer 10

@Ms-Brains You are there, correct?

Answer 11

Yeah! If you don't know how to do this, it's okay! I rather make sure it's correct. Than just get it done ;P

Answer 12

Alright, it's been a while since I've done this.

Quick question, has your course instructions covered anything like this before?

I'll try to help as much as i can

Answer 13

A little bit, they didn't really go in to detail about it.

Answer 14

shall i help?

Answer 15

hmmm

The inequality says <= to 6, so I am a bit confused on why the shading extends past 6

@Lovelarap If you can help, please feel free to join in

Answer 16

You can probably do this better than me

Answer 17

OK, first solve you equation for y

Answer 18

Oh and you can use this graph if you need visual aid @Lovelarap

Good luck @Ms-Brains !

Answer 19

\[3y \le-x+6\]
\[y \le -\frac{ 1 }{ 3 } +2\]

Answer 20

sorry, -1/3x

Answer 21

Here is a example my teacher gave us. If that helps.
My problem should look simlar this

Answer 22

it is just graph:
\[y \le -\frac{ 1 }{ 3 }x+2\]
It's solid because it is less than or equal to.

Answer 23

Which should equal to x < -3(y-2) ?

Answer 24

i think so.

Answer 25

How do I draw that on the Graph though. like in the example..?

Answer 26

Try https://mathway.com/.
It will help with the graphs

Answer 27

Okay..
So we got A figured out.

Answer 28

yep, now b

Answer 29

you remeber your other post where i helped you with the graph?

Answer 30

your line is It's solid because it is less than or equal to.

Answer 31

Oh! alright

Answer 32

Whenever it's equal to, it will always be solid

Answer 33

what do you think of c? below or above the line?

Answer 34

Wait.let me just write this down quickly.

Answer 35

Is this how the graph should look?

Answer 36

Yes it!

Answer 37

So On my paper, I circle the shade on the (2,) and (6,)?

Answer 38

yes

Answer 39

that's the x and y intercept

Answer 40

Okay, Now, what should I write in the B part?

Answer 41

you can write:
The line is is solid because it is less than or equal to.

Answer 42

Okay, And C?

Answer 43

You could say:
It is shaded below the line because it is less than.

Answer 44

Awesome!
I have 1 more problem I could use some help on.
