#### Explanation:

Under a reflection in the x-axis a point

#color(red)(|bar(ul(color(white)(a/a)color(black)((x,y)to(x,-y))color(white)(a/a)|)))# Under a reflection in the y-axis a point

#color(red)(|bar(ul(color(white)(a/a)color(black)((x,y)to(-x,y)color(white)(a/a)|)))#

#rArr(3,-5)to(3,5),(2,-1)to(2,1)" and " (4,3)to(4,-3)#
