question 4
what transformation is represented by the rule (x,y) into (x - 9, y + 2)?
translation 9 units to the right and 2 units up
translation 9 units to the right and 2 units down
translation 9 units left and 2 units down
translation 9 units left and 2 units up

Explanation:

In a coordinate - plane, for a transformation of the form $(x,y)\to(x - a,y + b)$ where $a>0$ and $b>0$, subtracting a positive number $a$ from the $x$ - coordinate moves the point $a$ units to the left, and adding a positive number $b$ to the $y$ - coordinate moves the point $b$ units up. Here $a = 9$ and $b=2$.

Answer:

Translation 9 units left and 2 units up
