The line segment AB has endpoint at A(5,-3) and B(2,-0) what are the vertices of the segment after it is reflected across the x axis?
A'( , )
B'( , )

the x's would stay the same, the y values are changed to their opposites
or (x,y) ----> (x, -y)
This is all dumb, speck Spanish.
To reflect a point across the x-axis, you need to keep the x-coordinate the same and change the sign of the y-coordinate.
Given the points A(5,-3) and B(2,-0):
To find the coordinates of A' after reflection, keep the x-coordinate of A the same, and change the sign of the y-coordinate. A' will have the coordinate (5, 3).
To find the coordinates of B' after reflection, keep the x-coordinate of B the same, and change the sign of the y-coordinate. B' will have the coordinate (2, 0) since the value of -0 is 0.
Therefore, the vertices of the line segment AB after reflecting across the x-axis are:
A' (5, 3) and B' (2, 0).
