Answer:
k=⅓
Explanation:
In order to find the scale factors of A(0,6) and B(9,3) to A'(0,2) and B'(3,1):
Find the differences in the x-coordinates and y-coordinates of the corresponding points:
- Δx = x-coordinate of B - x-coordinate of A = 9 - 0 = 9
- Δy = y-coordinate of B - y-coordinate of A = 3 - 6 = -3
Find the differences in the x-coordinates and y-coordinates of the new corresponding points:
- Δx' = x-coordinate of B' - x-coordinate of A' = 3 - 0 = 3
Δy' = y-coordinate of B' - y-coordinate of A' = 1 - 2 = -1
Calculate the ratio of the differences:
Scale factor = Δx'/Δx = 3/9 = ⅓
Theretscale factor (k) is ⅓.
