what is it..?

OpenStudy (pixiedust1):

I said the last one

jigglypuff314 (jigglypuff314):

yep :)

jigglypuff314 (jigglypuff314):

correct :)

jigglypuff314 (jigglypuff314):

yep :)

OpenStudy (pixiedust1):

P.S. Your profile is working again!! It just worked for me :D

OpenStudy (pixiedust1):

MINE IS WORKING TOO!! YAY! :D

jigglypuff314 (jigglypuff314):

YAY!!! :D :D :D glitches are finally being fixed xD

jigglypuff314 (jigglypuff314):

not quite...

OpenStudy (pixiedust1):

Oops! Do you know how I would solve this?

jigglypuff314 (jigglypuff314):

you can try plugging in the ordered pair to each option and see which one works... or you can see that lines parallel have equal slope the slope of y=x is 1 <- which slope matches this one? the slope of y=-x is negative 1 the slope of y=x+2 is 1 the slope of y=-x+2 is negative 1

OpenStudy (pixiedust1):

Oh! x+2

OpenStudy (pixiedust1):

Because the slope of x+2 is 1

jigglypuff314 (jigglypuff314):

yep! :)

OpenStudy (pixiedust1):

Yay!

jigglypuff314 (jigglypuff314):

slope of a perpendicular line would be the flipped opposite so 2/3 flipped is 3/2 then opposite (put a negative in front of it)

OpenStudy (pixiedust1):

Oh I forgot! Silly me! So it's 3/2?

jigglypuff314 (jigglypuff314):

negative 3/2 :)

OpenStudy (pixiedust1):

Oh yeah!! because then it becomes negative when it flips?

jigglypuff314 (jigglypuff314):

kinda... the slope of a perpendicular line in comparison to the original slope is just flipped and opposite... not necessarily that it becomes negative because it flipped.

jigglypuff314 (jigglypuff314):

not quite :) 3x + 2y - 6 = 0 in slope intercept form is y = -3/2 x +3 ^^

OpenStudy (pixiedust1):

Oh yeah! Because you gotta divide the 3 by 2, to isolate the y variable?

jigglypuff314 (jigglypuff314):

yep :) and don't forget the negative from moving the x to the other side :) ... I have 2 minutes.

OpenStudy (pixiedust1):

Oh okay! I'll hurry then. One problem per minute :D

jigglypuff314 (jigglypuff314):

2x + y = 4 --> y = -2x + 4 ^ so -2

OpenStudy (pixiedust1):

Oh yikes!! I keep forgetting lol! :D

OpenStudy (pixiedust1):

I don't wanna make you late

jigglypuff314 (jigglypuff314):

y does not have variable attached to it so no fractions

OpenStudy (pixiedust1):

Oh! So then its the last one

jigglypuff314 (jigglypuff314):

yep :)

OpenStudy (pixiedust1):

THANK YOU SO MUCH!

OpenStudy (pixiedust1):

HAVE AN AWESOME DAY!

jigglypuff314 (jigglypuff314):

you're welcome :) see ya later :D

OpenStudy (pixiedust1):

Okay! Bye!
