Question

MEDAL AND FAN PLEASE HELP!
Which of the following inequalities matches the graph?
A) The correct inequality is not listed.
B) 5x+y > or equal to 1
C) 5x+y < or equal to 1
D) 5x-y > or equal to 1

Answer 1

@kal122 do you know this one too?

Answer 2

A

Answer 3

how so? Can you explain?

Answer 4

Im really terrible at this kind of thing and I just wanna learn how :D

Answer 5

@JDizzle256

Answer 6

@SolomonZelman can you help me? Why is this question A?

Answer 7

Connection snapped, god dang it.

Answer 8

Okay, can you tell me the slope?

Answer 9

y=mx+b

Answer 10

Good, this is the slope intercept form, but what is the slope based on the graph?

Answer 11

I think we need to assign values for x and y

Answer 12

I do not know..... I do not see any points on the graph

Answer 13

Can you find the point, (0,0) and point (1,4) for me?

Answer 14

found them, if so, say "yes".

Answer 15

yes

Answer 16

the slope =?

Answer 17

y2-y1/x2-x1 so the answer would be 4

Answer 18

yes.

Answer 19

:D

Answer 20

So, lets start sketching the y-intercept form, as
y=4x

but we don't know the y-intercept, can you tell me the y-intercept? (where does the graph hit the x-axis?)

Answer 21

I mean filling in, not sketching.

Answer 22

0

Answer 23

yes, so we are getting,
\(\normalsize\color{black}{ y=4x}\)

Answer 24

Now, lets take care of the shading, where is it chaded, above or below the line?

Answer 25

the *shaded part.

Answer 26

both but more below

Answer 27

Yes, below:)

Answer 28

So, this would mean,
\(\normalsize\color{black}{ y\le4x}\) or \(\normalsize\color{black}{ y<4x}\)

Answer 29

y < 4x

Answer 30

now,
when the line is solid, we have \(\normalsize\color{black}{ \le}\) and \(\normalsize\color{black}{ \ge}\) .
and when the line is dashed, we have \(\normalsize\color{black}{ <}\) and \(\normalsize\color{black}{ >}\)

Answer 31

Your line is solid or dashed?

Answer 32

oh so y < or equal to 4x

Answer 33

its solid! :D

Answer 34

Yes:) \(\normalsize\color{black}{ y\le 4x}\)

Answer 35

so thats why its A :D

Answer 36

is that one of the options?

Answer 37

yes, right!!

Answer 38

I mean you can see already, that in options the slope is 5 or -5. So it is alredy wrong once you found the slope.

Answer 39

YAY thankies soooo much your the bestest! I have one more question can I ask you? Ill open another one so you can get 2 medals?

Answer 40

And you can see that it is wrong, by looking at the y-intercept.

Answer 41

:D ^_^

Answer 42

I don't care about medals:)

Answer 43

Whatever you want to.

Answer 44

But you earn them!!!! Your amazing! I open a new question and tag u!!!

Answer 45

Sure.
