Graphic image of the kite jklm after a reflection across the line Y= 1​
olchik [2.2K]

Answer:  see image

<u>Step-by-step explanation:</u>

Draw the line y = 1.  Count how many units away the point is from that line.  Move that point the same number of units in the opposite direction to create the reflection.

J is 2 units above y = 1. The new point is 2 units below y = 1.  →  (3, -1)

K is 3 units above y = 1. The new point is 3 units below y = 1.  →  (6, -2)

L is 5 units above y = 1. The new point is 5 units below y = 1.  →  (3, -4)

M is 3 units above y = 1. The new point is 3 units below y = 1.  →  (0, -2)
