Analyze the dilation below. What can be determined about the scale factor?

**Graph Analysis**

The graph presents a coordinate grid with two rectangles: rectangle ABCD (in red) and rectangle A'B'C'D' (in blue). The origin is at (0,0). 

**Rectangle ABCD (Red):**
- Points: A (2,3), B (5,3), C (5,1), D (2,1)
- Dimensions: Width = 3 units (from x=2 to x=5), Height = 2 units (from y=1 to y=3)

**Rectangle A'B'C'D' (Blue):**
- Points: A' (4,6), B' (10,6), C' (10,2), D' (4,2)
- Dimensions: Width = 6 units (from x=4 to x=10), Height = 4 units (from y=2 to y=6)

**Dilation Analysis:**
The blue rectangle A'B'C'D' is a dilation of the red rectangle ABCD. By comparing the dimensions:

- The width of ABCD (3 units) dilates to A'B'C'D' (6 units).
- The height of ABCD (2 units) dilates to A'B'C'D' (4 units).

**Scale Factor:**
The scale factor is determined by dividing the dimensions of A'B'C'D' by the dimensions of ABCD. Both width and height scale by a factor of 2 (6/3 = 2 and 4/2 = 2). Thus, the scale factor is 2.

This means rectangle ABCD is enlarged by a scale factor of 2 to form rectangle A'B'C'D'.
