A line containing the points (-2, 3)and ( 2, 3) is reflected across the x-axis how long is the reflected line? Is it infinitely long

The distance between the points (-2, 3) and (2, 3) is 4 units. When this line is reflected across the x-axis, it will still be 4 units long. The reflected line will extend infinitely in both directions along the x-axis.
