Question

write the coordinates of the vertices after a reflection over the y-axis.
k((
l(
m(

Explanation:

Step1: Find original coordinates

From the graph, \( K(-9,1) \), \( L(-9,4) \), \( M(-1,5) \).

Step2: Apply reflection rule

The rule for reflection over the \( y \)-axis is \( (x,y)\to(-x,y) \).
For \( K(-9,1) \): \( K'=(9,1) \)
For \( L(-9,4) \): \( L'=(9,4) \)
For \( M(-1,5) \): \( M'=(1,5) \)

Answer:

\( K'(9,1) \), \( L'(9,4) \), \( M'(1,5) \)
