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

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

$• " a point "(x,y)to(x,-y)$

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

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

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

A triangle has corners at (2, -7 )(2, -7 ), ( 1 , -3), and , and ( 4 , 3)#. What will the new coordinates of the triangle be if it is reflected across the x-axis?
