Which glide reflection describes the mapping triangle abc triangledef?

(x, y) mc117-7.jpg (x – 3, y) and reflected across x = 4
(x, y) mc117-5.jpg (x, y – 7) and reflected across x = 4
(x, y) mc117-6.jpg (x, y – 7) and reflected across x = 0
(x, y) mc117-8.jpg (x – 3, y) and reflected across y = 4

In order to visualize the transformations, we must execute the transformation in the options

The first transformation would shift triangle ABC 3 units to the left and reflect it across x = 4. This will not map ABC unto DEF.

The second transformation would shift triangle ABC 7 units down and reflect it across x =4. This will map ABC unto DEF,

So, the answer is the second option.
