When a point is reflected, it must be reflected across a line. The coordinates of the image of vertex D after a reflection across the x-axis is (5,3)
Given that:
[tex]D = (5,-3)[/tex]
The rule for reflection across the x-axis is:
[tex](x,y) \to (x,-y)[/tex]
So, we have:
[tex](x,y) \to (x,-y)[/tex]
[tex](5,-3) \to (5,3)[/tex]
This means that:
[tex]D' = (5,3)[/tex]
Hence, the coordinate of D' is (a) (5,3)
