**Question 4:**Diagram in the answer space shows a Cartesian plane board used in an indoor game.

The instruction of the game is such that the first move follows the translation $\left(\begin{array}{l}-4\\ -2\end{array}\right)$ and the second move follows the translation $\left(\begin{array}{l}\text{}5\\ -4\end{array}\right)$ .

Jimmy starts moving from the position mark x.

(a) Mark

*T*1 at Jimmy’s position after the first move and

*T*2 at the position after the second move.

(b) State the coordinates of the position based on Jimmy’s final move.

*Answer*:

*Solution*:**(a)**

**(b)**Jimmy’s final position = (3, –2).
