Question

May someone check my answer?

Answer 1

The slope is 4 and the y-intercept is -2

If I calculated correctly.

Answer 2

So then I put it into the slope intercept form: y=mx+b

Answer 3

I'm not entirely sure, but I think your correct.
Although I'd feel much better if @mathmale or @TheSmartOne or even @pooja195 could verify it.
I've never been a smarty for math, but looking at this somehow seems to make sense with your answer.

Answer 4

Thanks, @Atsie!

I plugged it in and it came out as y=-2x+4

Answer 5

Can you explain how you got 4 as the slope?

Answer 6

Wait, wouldn't it be negative 4...because of where the arrow runs onto the slope?

EEP!I could use a lesson!! :O

Answer 7

YIKES! I misread it!!! The y-intercept is 4!!! http://prntscr.com/9sbhf2

Answer 8

The slope is -2, I thought I put that in... :/

Answer 9

Now I'm getting confused. Let me read this again...

Answer 10

You did....
so negative 2 and negative 4
wouldn't D make more sense?
Or am I missing something myself?

Answer 11

Let me explain this to you...
Slope=rise over run
In the image below it is shown that we are rising two and going over one 2/1=2 slope=2x
It would be a negative slope if the line was decreasing but in this case it is increasing.

The line is touching the y axis at -4
NOT -2
Now make your equation.

Answer 12

y=4x-2 ?

Answer 13

Slope =mx
part of our equation
y=mx+b
m=slope
b=y intercept

Answer 14

It wouldn't be D because on D the slope is -2 which the slope isn't negative 2

Answer 15

The slope is negative
-2x

Answer 16

Yet the line is negative... :/

Answer 17

negative line=negative slope

Answer 18

Ohhhhh!!! So I am correct then?

Answer 19

Wait...

Answer 20

Yes with the -2x part

Answer 21

if you are confused with the slope then just take 2 points say \((x_1,~y_1)\) and \((x_2,~y_2)\) which lie on the graph and apply the slope formula->

\(\large slope= \frac{y_2-y_1}{x_2-x_1}\)

Answer 22

So i was wrong with the -4 part....?

Tis hard to teach an old new tricks :P

Answer 23

^^I did that already qwerty

So Pooja, My answer is correct then.

Answer 24

what is your answer?

Answer 25

Because it goes if you input it in slope-intercept form

B.

Answer 26

It's + B not - B.

Answer 27

They y intercept if -4

Answer 28

Seriously?

Answer 29

Ohhhhh!!! Wow. I wasn't paying attention... Let me check my answers again, @Pooja195.

Answer 30

I knew the slope was negative but I kept thinking the y-intercept was positive for some stupid reason.

Answer 31

No worries, :-)

The user already gave the answer but I hope you understand it :-)

Answer 32

IT IS???????????????

Its D.
?????????????

I understand myself now.

I'm dumb. -__-

Answer 33

I wasn't paying attention to @surjithayer, @Pooja195. Because I want to get this down.

Thank you for explaining it, @Pooja195! :)

Answer 34

yw ^.^
Thank @Atsie for attempting it and @imqwerty as well for showing you a different way :)

Answer 35

Thanks for being the teacher Ms. Pooja :)

Answer 36

if the line makes an obtuse angle with the positive side of x axis then the slope is negative
