Question

16 fill in the blank 1 point triangle ijk has the coordinates listed. i(5, -8) j(10, -8) k(7, -4) find j after a reflection over the y - axis. j: type your answer.. type your answer_

Explanation:

Step1: Recall reflection rule

The rule for reflecting a point $(x,y)$ over the $y - axis$ is $(-x,y)$.

Step2: Apply rule to point J

The coordinates of point J are $(10,-8)$. Using the reflection rule, when $x = 10$ and $y=-8$, the new $x -$coordinate is $-10$ and the $y -$coordinate remains the same. So the coordinates of $J'$ are $(-10,-8)$.

Answer:

$(-10,-8)$
