00:00:00.000 --> 00:00:03.000
Yes, I think it's going to be going to be a few of two.
2
00:00:03.000 --> 00:00:04.000
Ah, okay.
3
00:00:04.000 --> 00:00:06.000
All right, I'll see you next week.
4
00:00:06.000 --> 00:00:10.000
All right, what I'd like to do is show you how to set this into y-quals,
5
00:00:10.000 --> 00:00:13.000
or just slope in a sub-form, and then grab the equation.
6
00:00:13.000 --> 00:00:17.000
So, first thing we do, we need to understand what a slope in a sub-form.
7
00:00:17.000 --> 00:00:18.000
Well, slope in a sub-form.
8
00:00:24.000 --> 00:00:28.000
It is y equals m x plus b.
9
00:00:28.000 --> 00:00:34.000
Where m is our slope, m b is our y-winter sub.
10
00:00:34.000 --> 00:00:37.000
So, what I'm going to do is you can notice this is solved for y.
11
00:00:37.000 --> 00:00:38.000
So, that's what I need to do.
12
00:00:38.000 --> 00:00:45.000
So, I have 7x plus 6y minus 42 equals 0.
13
00:00:45.000 --> 00:00:49.000
So, what I'm going to do is, I mean, you get everything away except for the y.
14
00:00:49.000 --> 00:00:52.000
I'm going to add the 42 first to both sides.
15
00:00:52.000 --> 00:00:54.000
Now, it cancels out.
16
00:00:54.000 --> 00:00:59.000
So, I'm going to put 7x plus 6y equals 42.
17
00:00:59.000 --> 00:01:02.000
Now, I subtract the 7x on both sides.
18
00:01:02.000 --> 00:01:06.000
Now, we like to write, notice how the x is before our concept.
19
00:01:06.000 --> 00:01:12.000
For my b, so I have 6y equals a negative 7x plus 42.
20
00:01:12.000 --> 00:01:15.000
Then, I divide by 6.
21
00:01:15.000 --> 00:01:20.000
And, I'm going to divide the 6 into the negative 7x and the 6 into the 42.
22
00:01:20.000 --> 00:01:23.000
So, therefore, I have y.
23
00:01:23.000 --> 00:01:36.000
So, y equals a negative 7x plus 4x plus 42 divided by 6, which is 7.
24
00:01:36.000 --> 00:01:40.000
So, now, I have to ask this to graph this equation.
25
00:01:40.000 --> 00:01:47.000
So, I'll drive an x and a y-axis.
26
00:01:47.000 --> 00:01:50.000
And, when graph was solved with our sub form,
27
00:01:50.000 --> 00:01:55.000
if you can remember what the y-intercept is, the y-intercept is where the graph crosses my y-axis.
28
00:01:55.000 --> 00:01:57.000
So, it says, I'm going to cross that 7.
29
00:01:57.000 --> 00:01:58.000
So, I have about 7 units.
30
00:01:58.000 --> 00:02:01.000
1, 2, 3, 4, 5, 6, 7.
31
00:02:01.000 --> 00:02:06.000
And, I make a nice little dot there because I know that's exactly where my graph crosses.
32
00:02:06.000 --> 00:02:11.000
Then, it says my slope is a negative 7x.
33
00:02:11.000 --> 00:02:13.000
Now, that can mean a couple of things.
34
00:02:13.000 --> 00:02:17.000
Remember when slope is your change in your y.
35
00:02:17.000 --> 00:02:20.000
So, it's your rise over your run.
36
00:02:20.000 --> 00:02:26.000
So, you can either go down 7 to the right 6, or you can go up 7 to the left 6.
37
00:02:26.000 --> 00:02:31.000
Either way, one of your units is going to be negative, which makes your fraction negative.
38
00:02:31.000 --> 00:02:33.000
So, let's just do it this way.
39
00:02:33.000 --> 00:02:35.000
Let's start by going down 7.
40
00:02:35.000 --> 00:02:38.000
So, I can go down 7, 1, 2, 3, 4, 5, 6, 7.
41
00:02:38.000 --> 00:02:44.000
And, then, to the right 6, 1, 2, 3, 4, 5, 6.
42
00:02:44.000 --> 00:02:51.000
I'll make a dot there and I'll connect the two points.
43
00:02:51.000 --> 00:02:58.000
You also put a dot up 6, or 7, 1, 2, 3, 4, 5, 6, 7.
44
00:02:58.000 --> 00:03:00.000
And, then, go on left 6.
45
00:03:00.000 --> 00:03:03.000
1, 2, 3, 4, 5, 6.
46
00:03:03.000 --> 00:03:10.000
And, once you've noticed, if I were to get up and over, or right up there,
47
00:03:10.000 --> 00:03:14.000
you'd notice this graph, what I've done the exact same thing.
48
00:03:14.000 --> 00:03:17.000
You notice this line goes through those two points.
49
00:03:17.000 --> 00:03:21.000
So, whenever you have a negative, just remember, when you're either going down,
50
00:03:21.000 --> 00:03:26.000
which is negative, and to the right is positive, or you can go up, which is positive,
51
00:03:26.000 --> 00:03:29.000
and then, the left is going to be negative.
52
00:03:29.000 --> 00:03:34.000
So, whenever you have a negative slope, just either put the negative as a 7,
53
00:03:34.000 --> 00:03:39.000
that's going to tell you to go down 7 to the right 6, or make it a negative 6,
54
00:03:39.000 --> 00:03:42.000
which tells you to go up 7 to the left 6.
55
00:03:42.000 --> 00:04:11.000
So, that's how you solve this slope in a set form, and then graph.
