Okay, so i see that you need help with this question.
00:02
And for this it states, when two shapes, when you have two shapes to compare on a coordinate plane, you can determine the scale factor, knowing that the transformation was a dilation.
00:13
Generate instructions, you could give another student to determine the scale factor.
00:18
So to determine the scale factor, the scale factor, you are going to take the coordinates from your image.
00:36
So you're going to take your image coordinates, and which in this case is 2, 4.
00:52
And you are going to compare them.
00:58
So we're just going to take a and then a'.
01:01
And a ' is at 1, 2.
01:08
And you are going to compare them.
01:11
So write down image coordinates, that's step one.
01:19
Of two points, one for each image.
01:28
So, and you're going to take your pre -image coordinates, step two.
01:36
You're going to take your pre -image coordinates, and put them over your image coordinates...
