$2, 7), (1, 3) and (4, - 3)$ $2,7),(1,3)" and "(4,-3)$

Explanation:

$under a reflection in the x-axis$ $"under a reflection in the x-axis"$

$∙ a point (x, y) \to (x, - y)$ $• " a point "(x,y)to(x,-y)$

$\Rightarrow (2, - 7) \to (2, 7)$ $rArr(2,-7)to(2,7)$

$\Rightarrow (1, - 3) \to (1, 3)$ $rArr(1,-3)to(1,3)$

$\Rightarrow (4, 3) \to (4, - 3)$ $rArr(4,3)to(4,-3)$
