Given triangle jkl.

write the coordinates of vertex j and its reflection j' across the y-axis.

The coordinates of J are (-5, -2).

When reflected across the y-axis, the y-coordinate remains unchanged. The x-coordinate changes to 5.
Therefore the reflected coordinates of J are (5, -2).
The reflected image is shown in red color in the picture below.


After reflection across the y-axis, J' has coordinates (5, -2).

Answer is either b or c
