Question

The graph below is represented by which system of inequalities?
going to post picture.
Answers ;
-x + 3y < 9
y > -2x + 1

-x + 3y less than or greater to 9
y > -2x + 1

-x + 3y < 9
y greater than or equal to -2x + 1

None of these systems represent the graph shown.

Answer 1

ok let me see

Answer 2

alrighty. :)

Answer 3

can you first find the equation of those 2 lines?

Answer 4

why is the second set -x+3y less than or greater to??

Answer 5

you need to first solve for y in the first equation in 1st set

Answer 6

Okay , hold on.
1 ) -x+3y <9
+x +x
-----------
= 3y < 9x
/ 3 / 3
y < 3x


would you solve it like that ? or another way. i'm a bit confused about that.

Answer 7

ok so it would actually be y<1/3x +3 wouldn't it??

Answer 8

Ohhhhh. I'm seeing the vision.

Answer 9

yea

Answer 10

do u kinda get it or...

Answer 11

I kind of get it , but 'm getting there. It's the graph & corresponding them with the answers.I don't get.

Answer 12

oh ok. well in the first set, the two equations: one would have a y-intercept at 3 and the other @ 1. pretty sure u knew that

Answer 13

Indeed , I did.

Answer 14

:(

Answer 15

wish I could be of more help--- what do u specifically not understand?

Answer 16

ok I think that we can definitely eliminate the 3rd set right?

Answer 17

wait nvm

Answer 18

No.
It's fine.

Answer 19

Sorry for being an inconvience. I just don't get it.

Answer 20

its alright. u know all abt the shading of inequalities right?

Answer 21

No , not really.

Answer 22

oh well that has kind of a big part in inequalitites

Answer 23

lets say if u wanna check if an equality is true, u can choose any point on the graph(preferably 0,0) and if if it works in the inequality then u shade according to that

Answer 24

okay , so can I just plug in zero for each one ? To get the answer or a pont that's on the graph and plug it in ?

Answer 25

wait I don't get ur second set of linear equalities. why is one of them less than or greater to. u meant or equal to right?

Answer 26

less than or equal to , sorry for that.

Answer 27

oh ok that's fine :)

Answer 28

okay. i'm still confused.
never mind.
thank you for your time. :)
Sorry for the waste of time.

Answer 29

i feel really bad now. its kinda hard to explain like online or like when ur reading off something

Answer 30

like for me i learn when someone is next to me showing me how to do it and explaining... :(

Answer 31

im so sorry :(

Answer 32

i thought it was the 1st set though

Answer 33

It's okay. I passed the test with a 100 % so you did help.

Answer 34

yay!!! :) & no i didn't help
