A line containing the points (-2,3) ns (2,3) is reflected across the x-axis. How long is the reflected line?
A) 3 units
B) 4 units
C) not enough information
D) infinitely long
The reflected line across the x-axis will have the same length as the original line.
The distance between the points (-2,3) and (2,3) is 4 units.
Therefore, the length of the reflected line is also 4 units.
The answer is: B) 4 units
