Question

What are the coordinates of the point (5,3) reflected across the X-Axis

Answer 1

we you reflect a point across x-axis you do this

`(x,y)\longrightarrow(x,-y)`

so, the point (5,3) is

`(5,3)\longrightarrow(5,-3)`

to reflect across the x-axis you change the sign of the y coordinate

example

`(2,-1)\longrightarrow(2,1)`
