Okay, if the center of dilation of dilation is at zero, then you can just multiply your scale factor k.
00:25
I'm rather different.
00:27
Multiply k times your point x, y.
00:33
Okay.
00:34
So it says graph and label each figure, and it's, okay, so let me, i'm going to do one.
00:39
So negative four, one, two, three.
00:44
4 1 so that's a b is negative 2 1 2 3 1 2 3 1 2 3 so there's b c is 0 negative 2 which is here and d is negative 5 1 2 3 4 5 negative 2 1 2 so that's d all right so now i'm going to make all of these three times shorter.
01:26
So i'm going to do for a.
01:29
A is going to be three times negative four times one.
01:35
All right.
01:36
So that's going to give me negative 12, three.
01:42
So one, two, three, four, three, four, five, six, seven, eight, nine, ten, eleven, twelve, one, two, three.
01:59
These things are little bit for my eyes, my old eyes.
02:02
So there's a prime.
02:03
That's a.
02:05
All right.
02:06
The next one, negative 2.
02:08
So b is negative 2, 3.
02:11
And i'm going to multiply that times 3.
02:13
So it's going to give me negative 6, 9.
02:17
So 1, 2, 3.
02:19
1, 2, 3, 4, 5, 6.
02:27
1, 2, 3, 4, 5, 6, 7, 8, 9.
02:33
So that's b prime.
02:40
C prime.
02:43
So i've got three times zero negative two.
02:47
So that's going to be zero negative six.
02:52
Three, four...
