volunteer
Yeah, so then we found um a new point. So basically, it is 2 4/3.
11,999
463
[]
volunteer
um, and this is like the new point, but I just um wrote 4/3 is in like improper fraction, right?
11,999
464
[]
student
Mhm.
11,999
465
[]
volunteer
So I just wrote 4/3 as 1 and 1/3.
11,999
466
[]
volunteer
So 24/3 is the same as 21 and 1/3.
11,999
467
[]
volunteer
Does that make sense? Like, there's still
11,999
468
[]
volunteer
like both of these are like separate points.
11,999
469
[]
volunteer
Um, this is like the same thing as 2 and 24/3.
11,999
470
[]
student
has
11,999
471
[]
student
one
11,999
472
[]
volunteer
Yeah
11,999
473
[]
student
and 1/3
11,999
474
[]
volunteer
yeah.
11,999
475
[]
volunteer
It's like um uh like,
11,999
476
[]
volunteer
mixed fraction
11,999
477
[]
student
I understand it a little bit.
11,999
478
[]
volunteer
OK, wait, um
11,999
479
[]
volunteer
OK, so basically, we found um 1 1/3 by like
11,999
480
[]
volunteer
using the one as an X, right?
11,999
481
[]
student
Yeah
11,999
482
[]
volunteer
Yeah, and then we got like that point.
11,999
483
[]
volunteer
And then we basically wanted to find two, something.
11,999
484
[]
volunteer
So then that's what we did below, right?
11,999
485
[]
volunteer
Like the
11,999
486
[]
volunteer
ones on the left are the X values.
11,999
487
[]
volunteer
So first we did X is 0 and then we got Y is 0, so we're like.
11,999
488
[]
volunteer
choosing different X values and trying to find um a
11,999
489
[]
volunteer
Y value for each one.
11,999
490
[]
volunteer
So first we had 0 as our x value.
11,999
491
[]
volunteer
And then we um plugged in the 0.
11,999
492
[]
volunteer
and we got Y equals 0.
11,999
493
[]
volunteer
right?
11,999
494
[]
student
Yeah
11,999
495
[]
volunteer
Yeah, and then we did the same thing for the one, so we did.
11,999
496
[]
volunteer
Y equals 1/3.
11,999
497
[]
volunteer
times 12, and then we got 1/3, right?
11,999
498
[]
student
Yeah
11,999
499
[]
volunteer
Yeah, and then we're doing the same thing for the two, so we're doing Y equals 1/3 times 22. And then remember how we got 4/3 for that.
11,999
500
[]
student
Yeah
11,999
501
[]
volunteer
So then that would mean that this point is 24/3.
11,999
502
[]
volunteer
Right.
11,999
503
[]
volunteer
Yeah
11,999
504
[]
student
Yeah, yeah. I understand. Yeah, I understand.
11,999
505
[]
volunteer
Yeah, so then basically what I did is I just did
11,999
506
[]
volunteer
like 4/3 is the same thing as 1 and 1/3, like it's equivalent.
11,999
507
[]
volunteer
to that.
11,999
508
[]
student
OK
11,999
509
[]
volunteer
So then I got to comma 1 and 1/3. Does that make sense?
11,999
510
[]
student
Yeah
11,999
511
[]
volunteer
OK.
11,999
512
[]
student
So
11,999
513
[]
volunteer
So
11,999
514
[]
student
you, sorry, you
11,999
515
[]
student
you just, uh, OK, so the, the, this is a 2 is the X of the um.
11,999
516
[]
student
2 is the X.
11,999
517
[]
volunteer
yeah, 2 is the X of 4/3.
11,999
518
[]
student
And then you, you just put, you just find any number on the on the graph, like any number on the X.
11,999
519
[]
student
Um
11,999
520
[]
student
value
11,999
521
[]
volunteer
Yeah.
11,999
522
[]
student
OK, I unders. OK.
11,999
523
[]
volunteer
Yeah, you can, yeah, you just choose any number on the X axis, and then we can find a number for the Y.
11,999
524
[]
student
OK
11,999
525
[]
volunteer
Yeah.
11,999
526
[]
volunteer
OK. Um
11,999
527
[]
volunteer
so
11,999
528
[]
volunteer
then we can just
11,999
529
[]
volunteer
we, we can just graph 2 and 2 and 4/3.
11,999
530
[]
volunteer
So then we would get the point over there.
11,999
531
[]
volunteer
Does that make sense
11,999
532
[]
student
What did you say? I'm sorry
11,999
533
[]
volunteer
Yeah, um, so I just graphed the point 24/3.
11,999
534
[]
student
Mm
11,999
535
[]
volunteer
Like a graphed the point over here.
11,999
536
[]
volunteer
Wait
11,999
537
[]
volunteer
over here
11,999
538
[]
student
All right, good. Oh
11,999
539
[]
student
OK.
11,999
540
[]
volunteer
I, I plotted it. I plotted it on the graph.
11,999
541
[]
volunteer
Does that make sense
11,999
542
[]
student
we
11,999
543
[]
student
uh, which point is that?
11,999
544
[]
volunteer
Um, it's
11,999
545
[]
volunteer
so this is
11,999
546
[]
volunteer
this point
11,999
547
[]
volunteer
over there
11,999
548
[]
student
And then you point me to for like between 43, we went to x and y between 2, right?
11,999
549
[]
volunteer
Yeah, we plotted it.
11,999
550
[]
student
OK
11,999
551
[]
volunteer
Yeah.
11,999
552
[]
volunteer
OK. Do you have any, do you have any questions?
11,999
553
[]
student
No.
11,999
554
[]
volunteer
OK.
11,999
555
[]
volunteer
So
11,999
556
[]
volunteer
now
11,999
557
[]
volunteer
we can do the same thing with the axis of symmetry. So where would that be? Here.
11,999
558
[]
student
Sorry
11,999
559
[]
volunteer
It's
11,999
560
[]
student
What, what, what was your question?
11,999
561
[]
volunteer
Um, so where would the axis of symmetry be here?
11,999
562
