Question

timed problem
score: 4/5
reflection over the x - axis of the point (-9,5)
answer
(-5,-9)
(-9,-5)
(9,-5)
(-5,9)

Explanation:

Step1: Recall reflection rule

When reflecting a point $(x,y)$ over the x - axis, the x - coordinate remains the same and the y - coordinate changes its sign. The rule is $(x,y)\to(x, - y)$.

Step2: Apply the rule

For the point $(-9,5)$, with $x=-9$ and $y = 5$, after reflection over the x - axis, the new point is $(-9,-5)$ since the x - coordinate $-9$ stays the same and the y - coordinate $5$ becomes $-5$.

Answer:

$(-9,-5)$
