Question

what is the translation rule for sliding triangle abc? (use parenthesis)

Explanation:

Step1: Observe x - coordinate change

Let's take a vertex, say A. The x - coordinate of A in triangle ABC is 3 and in triangle A'B'C' is - 3. The change in x - coordinate is - 3 - 3=-6.

Step2: Observe y - coordinate change

The y - coordinate of A in triangle ABC is 1 and in triangle A'B'C' is 3. The change in y - coordinate is 3 - 1 = 2.

Answer:

(x,y)→(x - 6,y + 2)
