Reflections
A line containing the points (- 2, 3) and (2, 3) is reflected across the -axis. How long is the reflected line ? (1 point )
1 answer
The line is horizontal and its length is equal to the distance between the x-coordinates of the two points. Since the x-coordinate of both points is the same (3), the length of the reflected line is 2 - (-2) = 4 units.
