Answer:
Step-by-step explanation:
Given:
ΔA'B'C' image.
A (-1,2)
B (-1,-1)
C (-5,-10)
rule of translation(x,y) → (x + 1.5,y - 3.5)
This means that the given coordinates are the the sum of x and the difference of y.
A:
-1 = x + 1.5 → -x = 1.5 + 1 → -x = 2.5 → -x/-1 = 2.5/-1 → x = -2.5
2 = y - 3.5 → -y = -3.5 - 2 → -y = -5.5 → -y/-1 = -5.5/-1 → y = 5.5
A (-2.5 , 5.5)
B:
-1 = x + 1.5 → -x = 1.5 + 1 → -x = 2.5 → -x/-1 = 2.5/-1 → x = -2.5
-1 = y - 3.5 → -y = -3.5 + 1 → -y = -2.5 → -y/-1 = -2.5/-1 → y = 2.5
B (-2.5,2.5)
C:
-5 = x + 1.5 → -x = 1.5 + 5 → -x = 6.5 → -x/-1 = 6.5/-1 → x = -6.5
-10 = y - 3.5 → -y = -3.5 + 10 → -y = 6.5 → -y/-1 = 6.5/-1 → y = -6.5
C (-6.5, -6.5)
The pre image will have the following coordinates:
A (-2.5 , 5.5) ; B (-2.5,2.5) ; C (-6.5, -6.5)

Answer: -2, -2, -2, -2</h3>
Explanation:
If the common difference is 0, then we're adding 0 to each term to get the next term. However, adding 0 doesn't change the number. So that's why we have the same thing written four times.
As another example, let's say the common difference was 1 instead of 0. That would mean the first four terms are -2, -1, 0, 1 since we add 1 to each term to get the next one (eg: -2+1 = -1).
