Question

△jkl and its image are shown in the coordinate plane. enter the coordinates of the image after △jkl is reflected across the x - axis. jkl jkl j(-2,4) ? k(-2,2) ? l(-4,2) ?

Explanation:

Step1: Recall reflection rule

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

Step2: Find $J'$

For $J(-2,4)$, using the rule $(x,y)\to(x, - y)$, we get $J'(-2,-4)$.

Step3: Find $K'$

For $K(-2,2)$, using the rule $(x,y)\to(x, - y)$, we get $K'(-2,-2)$.

Step4: Find $L'$

For $L(-4,2)$, using the rule $(x,y)\to(x, - y)$, we get $L'(-4,-2)$.

Answer:

$J'(-2,-4)$
$K'(-2,-2)$
$L'(-4,-2)$
