00:01
All right, 56.
00:02
Let's do this system.
00:05
I can get me on a pin again.
00:07
I'm going to start with this vertical.
00:08
And hopefully remember that verticals are always x.
00:11
We are going that direction, which is greater than or equal to.
00:17
And the x value there is zero.
00:19
It looks like we've got another vertical line.
00:22
Vertical lines are cool because they're easy.
00:25
So we have x, although they're only easy once you finally figured out.
00:33
Some of us it takes a while to fear things out.
00:37
Just the other day i feared something.
00:39
I thought, man, i wish i'd known that 30 years ago.
00:42
But i didn't.
00:43
Okay, and here's a y, it's a horizontal.
00:46
So ys are going to be our horizontals, and that's why value is six.
00:55
Well, i have all those little things down there.
00:59
That's just interesting.
01:03
Evidently, computer, that's just an example.
01:07
I'll figure something out.
01:09
Where am i? i digress.
01:11
Oh, i want to do this one right here.
01:14
So, i want to, it's kind of a orangey color, don't you think? i'll make it a brighter orange.
01:21
Okay, so i'll make that one.
01:22
So we have a y intercept of three, and we have a slope of 1, 2, 3, negative 3 over 1, 2, 3, 4.
01:39
Okay.
01:44
Now, you could leave it like that.
01:46
If i remember correctly, all of the things that i've seen in your textbook, they have it in the standard form.
01:53
So what i'm going to do is multiply.
01:54
Everything comes four.
01:56
So 4y equals negative 3x plus 12.
02:03
Then i'm going to move that over the x over so that now you have 3x plus 4 .1.
02:13
And we're going this direction.
02:20
So we want, it's to be 12...
