Question

write the coordinates of the vertices after a reflection over the y - axis.

Explanation:

Step1: Recall the reflection rule

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

Step2: Find coordinates of \(K\)

The original coordinates of \(K\) are \((9, - 1)\). Using the reflection rule \((x,y)\to(-x,y)\), we get \(K'(-9,-1)\).

Step3: Find coordinates of \(L\)

The original coordinates of \(L\) are \((9,5)\). Using the reflection rule \((x,y)\to(-x,y)\), we get \(L'(-9,5)\).

Step4: Find coordinates of \(M\)

The original coordinates of \(M\) are \((6,-2)\). Using the reflection rule \((x,y)\to(-x,y)\), we get \(M'(-6,-2)\).

Answer:

\(K'(-9,-1)\), \(L'(-9,5)\), \(M'(-6,-2)\)
