Which describes how the transformation affects the coordinates of the vertices of trapezoid LMNO?

Group of answer choices
a. (x, y) → (x, −y)

b. (x, y) → (−x, −y)

c .(x, y) → (−x, y)

d. (x, y) → (x − 5, y − 2)

a. (x,y) -> (x,-y)

Step-by-step explanation:

Just by observing the graphs original and transformed shape, you can see that both graphs are in the same negative x-axis. Yet, the original is in the positive y-axis and the transformed is in the negative y-axis.

ddd

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
