timed problem
score: 2/5
reflection over the y - axis of the point (8, 9)
answer
(-8, 9) (-9, 8) (8, -9) (-9, -8)

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 $(8,9)$, where $x = 8$ and $y=9$, we change the sign of the x - coordinate. So, $(8,9)\to(-8,9)$.

Answer:

A. $(-8,9)$
