A line containing the points (−2, 3) and (2, 3) is reflected across the x -axis. How long is the reflected line?(1 point)Responses3 units3 unitsinfinitely longinfinitely longnot enough informationnot enough information 4 units
When a line is reflected across the x-axis, the y-coordinate of each point is negated while the x-coordinate remains the same.
The line containing the points (-2, 3) and (2, 3) is a horizontal line with a length of 4 units.
When reflected across the x-axis, the y-coordinate of both points becomes -3.
Therefore, the reflected line also has a length of 4 units.
So, the correct response is 4 units.
