The graph below represents which system of inequalities? graph of two infinite lines that intersect at a point. One line is solid and goes through the points (0, 2) (negative 2, 4) and is shaded in below the line. The other line is solid, and goes through the points (0, 2) (2, 0) and is shaded in below the line. y less than or greater to -2x + 3 y less than or greater to x + 3 y greater than or equal to -2x + 3 y greater than or equal to x + 3 y less than or greater to -3x + 2 y less than or greater to -x + 2 y > -2x + 3 y > x + 3

OpenStudy (help_people):

anybody mind helping hello?

OpenStudy (igreen):

Graph the options here: https://www.desmos.com/calculator

OpenStudy (igreen):

Tell me which one you get.

OpenStudy (help_people):

ok

OpenStudy (help_people):

I get c. Is that correct?

OpenStudy (help_people):

i green person are you still here

OpenStudy (help_people):

@iGreen

OpenStudy (igreen):

No.. C is wrong. https://www.desmos.com/calculator/danmi2vstd

OpenStudy (help_people):

is that the correct answer? @iGreen

OpenStudy (igreen):

No, C is incorrect.

OpenStudy (help_people):

then i do not know which one a and b are definitely not correct the only one is d?

OpenStudy (help_people):

but that is not correct?

OpenStudy (help_people):

i am pretty sure c is correct @iGreen

OpenStudy (igreen):

https://www.desmos.com/calculator/danmi2vstd This is the graph of C..that's incorrect.

OpenStudy (help_people):

what is correct then @iGreen

OpenStudy (nerdgirl):

Trust me when I say that C is correct.

OpenStudy (help_people):

@tkhunny @Nnesha what do you think?

OpenStudy (help_people):

thank you @Nerdgirl

OpenStudy (nerdgirl):

You're welcome. And you don't have to give me anything.

OpenStudy (help_people):

i am just really confused because @iGreen is telling me one answer and you are telling me another uuuuhhh

OpenStudy (help_people):

@phi can you help i think it is c what do you think?

OpenStudy (phi):

Your numbers in the question don't match up with the answers. can you check this: One line is solid and goes through the points (0, 2) (negative 2, 4) and is shaded in below the line.

OpenStudy (help_people):

ok so it is not c

Nnesha (nnesha):

"One line is solid and goes through the points (0, 2) (negative 2, 4) and is shaded in below the line. The other line is solid, and goes through the points (0, 2) (2, 0) and is shaded in below the line." both lines are not solid on the graph

OpenStudy (help_people):

d then

OpenStudy (phi):

I can't say yet. is the question correct ? do you really mean (0,2), (-2,4) ?

Nnesha (nnesha):

\(\color{blue}{\text{Originally Posted by}}\) @help_people d then \(\color{blue}{\text{End of Quote}}\) i'm saying statement doesn't match with the graph

OpenStudy (phi):

(0,2), (-2,4) gives a slope of (4-2) / (-2-0) = 2/-2 = -1 and y intercept of 2. shaded below a solid line means the relation is \[ y \le -x+2 \]

OpenStudy (help_people):

yes look at the graph i attached

OpenStudy (phi):

Is the graph what you are trying to decipher ?

OpenStudy (help_people):

yes

OpenStudy (phi):

because none of the lines in the graph go through (0,2)

OpenStudy (help_people):

i am using the graph to help me

OpenStudy (phi):

ok, can you say what is the y-intercept of the dotted line ?

OpenStudy (help_people):

i am so srry i posted the wrong graph this is all my fault hold let me look at my homework and make sure i get the correct graph

OpenStudy (phi):

Yes, please do that

OpenStudy (help_people):

this is the correct graph that i was using

OpenStudy (help_people):

the correct answer would be c .

OpenStudy (help_people):

@phi

OpenStudy (phi):

Yes, one line has a slope of -1 and y intercept of 2. solid, shaded below means \[ y \le -x+2\] the other has a slope of -3 and y-int of 2, also solid, shaded below \[ y \le -3x+2\] y less than or greater to -3x + 2 y less than or greater to -x + 2

OpenStudy (help_people):

@phi

OpenStudy (phi):

when you shade below the line, that means y is less than the y of the line

OpenStudy (phi):

if the line is solid we use less than *or equal* (the solid means the y could equal (be on) the line)

OpenStudy (help_people):

so c is correct

OpenStudy (phi):

yes, c is correct. But do you see how you can figure out the slope and the y-intercept and be able to write down the inequality? that is what you should be learning how to do.

OpenStudy (help_people):

ok thank you so much do you mind helping me again?

OpenStudy (phi):

If you make a new post.

OpenStudy (help_people):

ok
