Question

if this trapezoid is moved through the translation (x - 1, y + 1), the coordinate of a will be: a = ( ?, )

Explanation:

Step1: Find the original coordinate of point A

From the graph, the coordinate of point A is \((-6,2)\).

Step2: Apply the translation rule \((x - 1,y+1)\)

For the \(x\) - coordinate: \(x=-6\), after translation \(x'=-6 - 1=-7\).
For the \(y\) - coordinate: \(y = 2\), after translation \(y'=2 + 1=3\).

Answer:

\((-7,3)\)
