knock knock

OpenStudy (pixiedust1):

Hello! :D Who's that penguin knocking at my door? :D

OpenStudy (loser66):

do you know slope = \(\dfrac{rise}{run}\)

OpenStudy (pixiedust1):

Yup!

OpenStudy (loser66):

so, just take it, you should pick the point whose coordinate are integer like (1,5)

OpenStudy (pixiedust1):

Okay, so for the first one, I would do 5/1=5 -5/-1=5

OpenStudy (loser66):

1, is "goes to the east" , that means run 5 is goes to the north, that means rise

OpenStudy (pixiedust1):

Oh okay!

OpenStudy (loser66):

just pick 1 point,

OpenStudy (pixiedust1):

oh lol 5/1=5

OpenStudy (loser66):

yup, and the slope is the number stands in the front of x in the equation

OpenStudy (pixiedust1):

So 5x?

OpenStudy (loser66):

yup

OpenStudy (loser66):

DAT SIT

OpenStudy (pixiedust1):

lol!!! 4.) is similar, but it looks harder!!

OpenStudy (loser66):

Yes, it's hard

OpenStudy (pixiedust1):

Can you help me with maybe one of the general form questions? I got NO idea how to solve those lol

OpenStudy (loser66):

be honest, I don't know how to solve, y -intercept, check, but the slope is not correct

OpenStudy (loser66):

@SolomonZelman

OpenStudy (pixiedust1):

That's fine! I got no idea how to solve them either lol :D

OpenStudy (loser66):

get others help, why not?

OpenStudy (pixiedust1):

Yup! Thanks my Penguin bro!

OpenStudy (loser66):

please, help us. I want to know what is wrong with me, too.

OpenStudy (loser66):

It's not finding y intercept; we have to define which is the equation of the given line

OpenStudy (loser66):

for problem 4

OpenStudy (pixiedust1):

Oh okay!

OpenStudy (loser66):

@experimentX

OpenStudy (pixiedust1):

@myininaya @Mertsj

OpenStudy (loser66):

@Mertsj what do you think?

OpenStudy (mertsj):

For problem 4 all choices have same y intercept which is - 13/3. Slope of the line is obviously negative so it has to be the third choice.

OpenStudy (loser66):

no Mertsj, (-5,-1) gives us slope = 1/5

OpenStudy (mertsj):

Are we talking about problem 4 or not?

OpenStudy (loser66):

yes, problem4

OpenStudy (pixiedust1):

Oh okay! That makes sense ! Thanks

OpenStudy (pixiedust1):

(Sorry my computer is lagging)

OpenStudy (experimentx):

?? can you copy paste your question or post screen shot? i hate to download that pdf

OpenStudy (mertsj):

The point (-2,-3) is also on the line so find the slope using the points (-5,-1) and (-2,-3)

OpenStudy (pixiedust1):

@experimentX - would a word doc be better?

OpenStudy (loser66):

oh, I got you. I take my question back, hehehe @Mertsj

OpenStudy (pixiedust1):

Thank you all. So we all agree that #4 is the last answer option?

OpenStudy (loser66):

yup

OpenStudy (pixiedust1):

Yay! Thanks everyone!

OpenStudy (experimentx):

@Loser66 jpg/png :D

OpenStudy (loser66):

@experimentX what do you mean?
