When a point is reflected across the x-axis, the x-coordinate stays the same, but the y-coordinate is negated.
The original point is (2, 3).
After reflecting across the x-axis, the new point will be (2, -3).
To find the length of the reflective line, we need to measure the distance between the original point (2, 3) and the reflected point (2, -3) along the y-axis.
The distance between two points along the y-axis can be found by subtracting the y-coordinates. In this case, it is |-3 - 3| = 6 units.
Therefore, the reflective line is 6 units long.
Avon change the points -2, 3 and 2, 3 is reflected across the x-axis how long is the reflective line
