The coordinates of point A on a grid are (5, −3). Point A is reflected across the x-axis to obtain point B. The coordinates of point B are (5, ___)

Respuesta :

(5,3) if its just reflecting across the x axis the negative will turn to positive
mathmate
The rule for reflection about the x-axis is
(x,y) -> (x,-y)

=>

reflection of A(5,3) according to the rule is
A(5,-3) -> A'(5,3)

Note: edited to correct for inversion of coordinates.
