1. Problem Description

The problem states that triangle JKLJ'K'L' is a dilation of triangle JKLJKL. We need to find the scale factor of the dilation.

2. Solution Steps

The scale factor of a dilation can be found by dividing the length of a side in the image by the length of the corresponding side in the pre-image. We can find the coordinates of the vertices of the triangles from the graph.
J=(3,4)J = (-3, 4)
K=(3,4)K = (-3, -4)
L=(1,4)L = (1, -4)
J=(6,8)J' = (-6, 8)
K=(6,8)K' = (-6, -8)
L=(2,8)L' = (2, -8)
Let's find the length of side JKJK and side JKJ'K'.
The length of JKJK is 4(4)=84 - (-4) = 8.
The length of JKJ'K' is 8(8)=168 - (-8) = 16.
The scale factor is the ratio of the lengths of the corresponding sides:
k=JKJK=168=2k = \frac{J'K'}{JK} = \frac{16}{8} = 2
Alternatively, we could find the distance from the origin to each point. If we assume the center of dilation is at the origin (0,0), we can check the scale factor by comparing coordinates.
J=(3,4)J = (-3, 4), J=(6,8)J' = (-6, 8). Since 32=6-3*2 = -6 and 42=84*2 = 8, the scale factor is

2. $K = (-3, -4)$, $K' = (-6, -8)$. Since $-3*2 = -6$ and $-4*2 = -8$, the scale factor is

2. $L = (1, -4)$, $L' = (2, -8)$. Since $1*2 = 2$ and $-4*2 = -8$, the scale factor is

2.

3. Final Answer

The scale factor of the dilation is 2.
