Henry starts with the two parallel line segments shown. She correctly reflects the segments across the x-axis and then translates them following the rule (x,y) --> (x-2,y+5). Which statements about the reflection and translation of the line segments are true? Select all that apply

• The final image will result in parallel segments slanted in the opposite direction and the same distance apart as the preimage segments.

• The coordinates of point C’ in the final image are (1,4).

• When reflected over the x-axis, the coordinates of point A become (2,–4).

• The final image will result in perpendicular segments that intersect at point (0,1).

• The final image will result in parallel segments slanted in the same direction and closer together than the preimage segments.
