Question

question what is the image point of (-5,3) after the transformation $d_{\frac{1}{3}} circ t_{-4,3}$? answer attempt 1 out of 2

Explanation:

Step1: 先进行平移变换

先对点\((-5,3)\)进行\(T_{ - 4,3}\)平移变换,根据平移公式\((x,y)\to(x - 4,y + 3)\),则\((-5,3)\to(-5-4,3 + 3)=(-9,6)\)。

Step2: 再进行缩放变换

对\((-9,6)\)进行\(D_{\frac{1}{3}}\)缩放变换,根据缩放公式\((x,y)\to(\frac{1}{3}x,\frac{1}{3}y)\),则\((-9,6)\to(\frac{1}{3}\times(-9),\frac{1}{3}\times6)=(-3,2)\)。

Answer:

\((-3,2)\)
