So for this problem, it says here's a polygon on the grid.
00:04
Well, there was no polygon and there was no grid.
00:07
So i'm going to create a polygon, and i'm going to do the items that would happen to the polygon if it was here.
00:18
So i'm just going to make one up.
00:20
So the polygon that i'm going to make up is going to be, we'll have a, be at 4, 2, b, be at 6.
00:30
Actually, no, i'm going to go smaller.
00:32
So hold on because my graph is not that big.
00:39
So i'm going to have a be at 2 -2.
00:47
B is going to be at 3 -3, or actually be at 1 -1.
01:01
C is going to be at 1 -2.
01:06
And let's see, d will be at 2 .0.
01:23
So here's my polygon.
01:27
So i'm just going to put what the coordinates are, c, d.
01:33
So a is at 22, b is at 1 -1, c is at 1 -1, c is at 1 -2, and d is going to.
01:49
To be at 02.
01:54
So if i have to make a scaled copy of the polygon using a scale factor of 3, so for a scale factor of 3, what you're going to do is you're going to multiply your coordinates by 3.
02:14
So a would be at 6 .6, b would be at 3, 3, and c prime would be at 3, and c prime would be at 3 comma negative 6 and d prime would be at 0 .6 so i'm going to plot those points because it wants me to draw them too so 66 is going to be a prime b prime is at 3 3 3.
02:49
C prime is at 3 negative 6 and d prime is at 0 6.
02:58
Okay.
03:07
And then it says draw a scaled copy of the polygon with a scale factor of one half and label it b...
