Question

1. what is the error after graphing the image below of triangle abc after the translation (x,y)→(x - 1,y - 2).

Explanation:

Step1: Analyze the translation rule

The translation rule is \((x,y)\to(x - 1,y - 2)\), which means moving 1 unit to the left and 2 units down.

Step2: Check the graph visually

Looking at the graph of triangle \(ABC\) and its supposed - translated image, we can observe the movement of vertices. If we assume a vertex of \(\triangle ABC\) has coordinates \((x_0,y_0)\), its new coordinates after translation should be \((x_0 - 1,y_0 - 2)\).

Step3: Identify the error

The error is that the triangle has been translated 1 unit to the right instead of 1 unit to the left (since the \(x\) - coordinate in the translation rule is \(x-1\) which means subtracting 1 from the \(x\) - coordinate of each point, corresponding to a left - ward movement).

Answer:

The triangle has been translated 1 unit to the right instead of 1 unit to the left as per the translation rule \((x,y)\to(x - 1,y - 2)\).
