2. 64 in * k = 160 ft
160 ft X 12 in = 1920 in
64 in * k = 1920 in
k = 𝟏𝟗𝟐𝟎 𝟔𝟒
k = 30

6. Today’s Objective:
I understand how changing a function is reflected in its graph.

7. Center of Dilation
The center of dilation is a fixed point in the plane about which all points are expanded or contracted.

8. Let’s Review Dilations:
a transformation
retains the shape
has a different size
has a center of dilation and a scale factor
k > 1, the image is an enlargement
0 < k < 1 the image is a reduction
Notation (k): 𝒙,𝒚 →(𝒌𝒙,𝒌𝒚)
