A) 40
B) 30
C) 20
a) 10 and 4
b) 10 and 6
c) 10 and 8
Answers:
C) 20 —-> a) 10 and 4
B) 30 —-> b) 10 and 6
A) 40 —-> c) 10 and 8
Explanation:
20: 10 x 2 = 20 ; 4 x 5 = 20
30: 10 x 3 = 30 ; 6 x 5 = 30
40: 10 x 4 = 40 ; 8 x 5 = 40

Answer:
The scale factor is 1/3
Explanation:
Given that the original point is has coordinates (x,y) and that the dilated point has coordinates (x',y'), we can see that:
x' = k * x
y' = k * y
where k is the scale factor
Now, for the given point we have:
original point = (6 , -3)
dilated point = (2 , -1)
Now, applying the above formula, we will find that:
For x-coordinate:
2 = k * 6
k = 2/6
k = 1/3
Check using the y-coordinate:
-1 = k * -3
k = -1 / -3
k = 1/3
From the above, we can confirm that:
k = 1/3
Hope this helps :)
