Which transformation is shown below?7BB.2coСdu43-2-1257e.--23A translation of four units to the left.O A translation of four units to the left and three units down.O A reflection across the line y = 3.O A reflection across the line x = 2.ok

Ok, so
Here we have the following figure.
Notice that each point of the blue graph, is located at the same distance of the point of the green graph across the line x=2.
For this reason, there's a reflection across the line x=2.
