Question

1. △rst is a translation image of △rst. what is the coordinate rule for the translation? (x,y)→(x + 3,y - 7) (x,y)→(x + 7,y - 3) (x,y)→(x - 7,y + 3)

Explanation:

Step1: Select a point

Let's take point \(S(4,2)\) and its image \(S'(- 3,5)\).

Step2: Calculate x - coordinate change

The change in the x - coordinate is \(-3−4=-7\).

Step3: Calculate y - coordinate change

The change in the y - coordinate is \(5 - 2=3\).

Answer:

\((x,y)\to(x - 7,y + 3)\)
