@vaiker im pretty sure i got 2 and 3 for possible answers for a and b
a=2, b=3
When you put it into standard form and multiply both sides by 3, you would get:
2x - 3y = 9
Therefore, a = 2 and b = 3.
which english section was experimental?
@splashzone10 I was most unsure about this one cuz I got 1, which seemed unusual to me.
My reading experimental was about Egyptian stuff
@Periso That is what I though too. She swears she had no grid in sections. - My daughter had 4 CR sections so we know one was experimental. She was hoping it was Japanese Poem one. She thought it was tough! Another poster thought the experimental was the one on the Cold War. Of course she thought that one was easy!
@2kidzmom @pesiro
I can confirm, Japanese is NOT experimental.
@hickey
Did you have 4 math sections???
@2kidzmom
I actually didn’t get a Cold War section, so that is probably an experimental section.
There is always a grid-in section by the way:

@splashzone10 I honestly am not sure. I think I only had 3 and 4 writing. Why?
What was the answer to the CR question about the quote “Time travel” in the train question?
And for the quadrant where the two lines intersected, I think I got quadrant 4 actually lol
I got two 35-question Writing sections, along with a 14-minute Section 10, so does that mean that one of the Writing was an experimental for me? Is there usually only 1 35-question Writing section?
@andy276153
I got Quadrant 4 as well
@PartyNextDoor
Yes, you got an experimental section in writing.
@vaiker Yeah you just multiply everything by 3 to get rid of the fraction on -2/3x, and then since it was in y=mx+b form you just move the x variable to the left side to get standard form (Ax + By = C).
The Egyptian passage was obviously the experimental since there was a graph
@Periso Thanks 
My first math section was Experimental with charts and stuff, it was grid-in.
And missing 1 on math grid-in is the same as omitting a regular multiple choice question, right?
If anyone knows what the math experimental is, please help.
@hotpepperseed That was not experimental lol, I had it too. Yeah it was hard.
