• 00:00 - 00:01

  Hello. Hello, guys.

• 00:02 - 00:05

  And welcome toe another video where we're gonna discuss a

• 00:05 - 00:07

  topic that we learned in unit eight.

• 00:07 - 00:08

  Coordinate planes.

• 00:09 - 00:11

  So today's video go is two things.

• 00:12 - 00:14

  First, we're going to discuss what is an ordered pair,

• 00:15 - 00:17

  and then suddenly we're gonna discuss how do you determine

• 00:18 - 00:20

  which Roger and Order Perry's in?

• 00:21 - 00:23

  We have noticed that you guys have great mastery and

• 00:24 - 00:26

  determine where in order parents in the first Quadrant.

• 00:27 - 00:31

  But we recently learned there's actually four quadrants co ordinate

• 00:32 - 00:34

  plane. Now we need to make sure you have guys

• 00:34 - 00:38

  have mastery in all four quadrants before we dive into

• 00:38 - 00:41

  that. Let's just have a quick, real quick recap on

• 00:41 - 00:42

  what's an ordered pair.

• 00:44 - 00:47

  So right here is an order pit, and it's really

• 00:47 - 00:49

  important that you do not forget it, because if you

• 00:50 - 00:52

  confuse the order of an ordered pair, you're gonna end

• 00:52 - 00:56

  up getting every single question wrong on your homework's your

• 00:56 - 00:58

  exit tickets and eventually your quist.

• 00:59 - 01:00

  So let's go.

• 01:00 - 01:04

  Disgusted and order pair is where the X coordinate is

• 01:04 - 01:07

  first, and then the why quoted it is second and

• 01:07 - 01:07

  here's an example.

• 01:10 - 01:14

  So right here we have the 0.6 comma, four and

• 01:14 - 01:17

  the beauty about the X coordinate and let you know

• 01:17 - 01:19

  how far from the y axis you are.

• 01:19 - 01:21

  And if you look closely, you see that at this

• 01:21 - 01:27

  point is actually six minutes away from the why and

• 01:27 - 01:29

  then the why according it.

• 01:30 - 01:32

  Well, that lets you know how far from the X

• 01:32 - 01:33

  axis you are.

• 01:33 - 01:36

  If you look closely, you see that six comma four

• 01:36 - 01:40

  is actually four units away from the X axis.

• 01:40 - 01:42

  And that's always a great way for you to determine

• 01:43 - 01:44

  where to plot your points.

• 01:44 - 01:47

  If you know what your X coordinate is, u doesn't

• 01:47 - 01:48

  need no help for formal.

• 01:48 - 01:51

  Why access your and you know your wife corn in

• 01:51 - 01:53

  it? You know how far you are from as active.

• 01:55 - 01:57

  So now that would discuss what an ordered pair is

• 01:58 - 02:02

  not determined discussed the quadrants and their rules.

• 02:03 - 02:07

  So for question one, the X coordinate is positive, and

• 02:07 - 02:08

  the Y coordinate is positive as well.

• 02:09 - 02:11

  And when you head over to the second quadrant your

• 02:11 - 02:13

  ex quarter, that becomes negative.

• 02:13 - 02:14

  But your wife did.

• 02:14 - 02:17

  It remains possible that you won't have the third cup

• 02:18 - 02:18

  part it.

• 02:18 - 02:21

  Where is just of a huge negative, Nancy everything's negative

• 02:21 - 02:21

  every day.

• 02:22 - 02:24

  The expert in it and the white corner are both

• 02:25 - 02:25

  going to be negative.

• 02:26 - 02:30

  And then last year, quarter for where it's gonna be

• 02:30 - 02:33

  positive and exported it and the white negative in the

• 02:33 - 02:33

  white corner.

• 02:35 - 02:36

  So that's why it's really important.

• 02:36 - 02:39

  You do not forget the order of an ordered pair

• 02:39 - 02:43

  because if you flip to, you're always gonna determine, um,

• 02:44 - 02:45

  the wrong quadrant for your ordered pairs.

• 02:47 - 02:48

  So this is doing exam.

• 02:49 - 02:51

  How can we determine which quadrant is the point?

• 02:52 - 02:54

  Negative three common to located it.

• 02:55 - 02:57

  So before we discuss anything that just look at the

• 02:57 - 03:01

  first home co ordinate negative three, that lets me know

• 03:01 - 03:03

  my ex Corde in it, it's negative.

• 03:03 - 03:05

  So what I'm gonna do right away, I'm gonna go

• 03:06 - 03:06

  back to that truck.

• 03:06 - 03:09

  We just have this one right here, and I'm gonna

• 03:09 - 03:10

  make some eliminations.

• 03:11 - 03:13

  I own my expert in his negative, So there's no

• 03:14 - 03:17

  way that my point is going to be in quadrant

• 03:17 - 03:18

  what are watching for?

• 03:19 - 03:24

  Because if you look closely, those Hodgins you're exporting is

• 03:24 - 03:24

  going to be positive.

• 03:25 - 03:27

  But we already know our expert.

• 03:28 - 03:29

  It is negative Three, which is negative.

• 03:30 - 03:33

  So what I'm gonna do right away, just like on

• 03:33 - 03:34

  a multiple choice question.

• 03:34 - 03:36

  I'm going eliminate those two options.

• 03:37 - 03:38

  There's no way I'm gonna get trick.

• 03:38 - 03:39

  And neither should you.

• 03:40 - 03:41

  What about our wide quarter?

• 03:42 - 03:42

  Well, are white.

• 03:43 - 03:43

  According it was positive.

• 03:44 - 03:47

  So no, what I'm gonna do, I don't Questions two

• 03:47 - 03:47

  and three.

• 03:48 - 03:48

  Which one you think?

• 03:48 - 03:49

  Can we eliminate now?

• 03:50 - 03:51

  So I'm actually give you a second to think about

• 03:51 - 03:54

  that. And let me just make this a little bigger

• 03:55 - 03:55

  for you guys.

• 03:59 - 04:03

  Exactly. We could eliminate Quadrant three and just like a

• 04:04 - 04:04

  multiple choice.

• 04:04 - 04:05

  Question What?

• 04:05 - 04:08

  You eliminate your other three options, you know?

• 04:08 - 04:08

  Know your answer.

• 04:09 - 04:12

  So the correct answer is this point is indeed in

• 04:12 - 04:14

  Quadrant two.

• 04:16 - 04:18

  So now I want you to try this on your

• 04:18 - 04:22

  own. Which quadrant is the 0.4 negative six.

• 04:22 - 04:24

  Located it and sketch stuff.

• 04:24 - 04:27

  Just re watch this video, and hopefully you are able

• 04:27 - 04:29

  to be a be able to answer this question.
