Which statement about the slope of the line is true? It is –2 throughout the line. It is fraction negative 1 over 2 throughout the line. The slope from point O to point A is one-half times the slope of the line from point A to point B. The slope from point O to point A is two times the slope of the line from point A to point B.

@lall

OpenStudy (anonymous):

do you know how to do this?

OpenStudy (sleepyjess):

Would you agree that this line has the same slope for the entire line?

OpenStudy (anonymous):

yea

OpenStudy (sleepyjess):

Okay, do you know how to find slope?

OpenStudy (anonymous):

mx+b

OpenStudy (sleepyjess):

That is slope-intercept equation of a line

OpenStudy (anonymous):

oh i guess i forgot

OpenStudy (sleepyjess):

\(m=\dfrac{x_2-x_1}{y_2-y_1}\)

OpenStudy (sleepyjess):

Flip flop that, it should be y2-y1/x2-x1

OpenStudy (anonymous):

i dont really understand but i think its C or D

OpenStudy (sleepyjess):

C and D both have 2 slopes

OpenStudy (anonymous):

oh wait B right

OpenStudy (sleepyjess):

Do you understand the formula?

OpenStudy (anonymous):

haha yes

OpenStudy (anonymous):

do you want to plug it in then im just so tired its 5 am and im trying to get this done im not really thinking right im sorry

OpenStudy (anonymous):

im giving a medal just saying

OpenStudy (sleepyjess):

Let's use point A(-4, 2) as (x1, y1) and point O(0, 0) as (x2, y2)

OpenStudy (anonymous):

ok

OpenStudy (sleepyjess):

So what is y2-y1?

OpenStudy (anonymous):

0,2

OpenStudy (sleepyjess):

Subtract them

OpenStudy (anonymous):

ohh 2

OpenStudy (anonymous):

i swear im like half asleep lol so sorry

OpenStudy (sleepyjess):

0-2

OpenStudy (anonymous):

-2

OpenStudy (anonymous):

sorry ik im probably being a pain in the butt cut me some slack tho ive been up since 9:45 amand now its almost 6am im a hard woker

OpenStudy (sleepyjess):

Yes! Now x2-x1?

OpenStudy (anonymous):

4

OpenStudy (sleepyjess):

Yes! So what is -2/4 simplified?

OpenStudy (anonymous):

-1/2

OpenStudy (anonymous):

B!!!!

OpenStudy (sleepyjess):

Yes! So that would be option...

OpenStudy (anonymous):

yayy

OpenStudy (sleepyjess):

Yeah!! :)

OpenStudy (anonymous):

i have two more should i post them or just put them here? would you help me with them too please?

OpenStudy (sleepyjess):
