Which figure represents the image of parallelogram LMNP after a reflection across the line y = X?

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

$12. that is my answer.

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7
