Question

Point B is located at (-5, -5) on the coordinate plane. Point B is reflected over thex-axis to create point B'. What ordered pair describes the location of B'?

Answer 1

If a coordinate is refleted over the x-axis, the formula to apply is

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

So for B(-5, -5), this becomes

`\begin{gathered} B\mleft(-5,-5\mright)\rightarrow(-5,-(-5) \\ \\ the\text{ answer becomes } \\ \\ B(-5,-5)\rightarrow B^(\prime)(-5,5) \end{gathered}`
