Jika Titik C(-7,5) dirotasikan sejauh 90° searah jarum jam dengan pusat O(0,0) kemudian ditranslasikan T= 3 −4 , maka bayangannya adalah …. (-3,8) (-8,3) (8,-3) (8,3) (-8,-3)

A rotation of 90° clockwise around the origin transforms a point $(x,y)$ to $(y, -x)$.
For C(-7,5):

$$C' = (5, -(-7))$$ $$C' = (5, 7)$$

The translation vector is $T = \begin{pmatrix} 3 \\ -4 \end{pmatrix}$.
A translation by vector $\begin{pmatrix} a \\ b \end{pmatrix}$ transforms a point $(x,y)$ to $(x+a, y+b)$.
For C'(5,7) and $T = \begin{pmatrix} 3 \\ -4 \end{pmatrix}$:

$$C'' = (5 + 3, 7 + (-4))$$ $$C'' = (8, 7 - 4)$$ $$C'' = (8, 3)$$

The final image of the point is (8,3).
