Answer :
Answer:
The coordinates of point B are (5, 3).
Step-by-step explanation:
Given:
The coordinates of point A on a grid is (5, -3).
The point is reflected across the x-axis.
When a point [tex]A(x,y)[/tex] on a grid is reflected across the x-axis, the coordinate rule for the reflected point B is given as:
[tex]A(x,y)\rightarrow B(x,-y)[/tex]
Therefore, the 'y' value changes sign upon reflection across the x-axis.
Here, [tex]x=5,y=-3[/tex]
Hence, the coordinates of point B are (5,-(-3)) = (5, 3)
