Question

question what is the image of (9, -7) after a reflection over the y - axis? answer attempt 1 out of 3 (, ) submit answer

Explanation:

Step1: Recall reflection rule

When reflecting a point $(x,y)$ over the $y - axis$, the rule is $(x,y)\to(-x,y)$.

Step2: Apply the rule

For the point $(9, - 7)$, where $x = 9$ and $y=-7$, we change the sign of the $x - coordinate$. So $x = 9$ becomes $-9$ and $y=-7$ remains the same.

Answer:

$(-9,-7)$
