WebSo for example, let's think about point D first. Point D is at negative 8. So if we have a scale factor of 1/2, what point D will map to is going to be at negative 4 on the x direction. And on the y direction, D is at negative 9, so this is going to be at negative 4.5. Half of that. So that is going to be right over there.
