The reflected line will have the same length as the original line.
To find the length of the line, we can use the distance formula:
d = √((x2 - x1)^2 + (y2 - y1)^2)
Using the points (-2, 3) and (2, 3), we have:
d = √((2 - (-2))^2 + (3 - 3)^2)
= √((4)^2 + (0)^2)
= √(16 + 0)
= √16
= 4 units
Therefore, the length of the reflected line is 4 units.
