Question

△vwx is a translation of △vwx. write the translation rule. (x, y) → (x + □, y - □)

Explanation:

Step1: Determine x - translation

Count the horizontal shift from a point in $\triangle VWX$ to its corresponding point in $\triangle V'W'X'$. For example, point $X(-8,9)$ and $X'(1,0)$. The change in $x$ - coordinate is $1-(-8)=9$. So the $x$ - part of the translation rule is $x+9$.

Step2: Determine y - translation

Count the vertical shift from a point in $\triangle VWX$ to its corresponding point in $\triangle V'W'X'$. Using the same points $X(-8,9)$ and $X'(1,0)$, the change in $y$ - coordinate is $0 - 9=- 9$. So the $y$ - part of the translation rule is $y - 9$.

Answer:

$(x,y)\to(x + 9,y - 9)$
