## Question 1

*Leaving the center of dilation, point D, at (0, 0), point A at (0, 3) and point B at (3, 0), adjust the scale factor k to 2, 3, 4 and 5. *
**What are you noticing about the slope of AB compared to A'B'?**

## Question 2

*Leaving point A at (0, 2), move point B to (4, 3) and move the center of dilation, point D, so that is is on line segment AB at (2, 3). Adjust the scale factor, k, to 0.5, 2, 3, and 4.*
**
What do you notice about the length and location of A'B' compared to AB?**

## Question 3

**How would you summarize the differences in the dilated line when the center of dilation is ON the preimage line versus NOT ON the preimage line?**
