Answer:
[see below]
Step-by-step explanation:
Reflection across the x-axis is: [tex](x,y)\rightarrow(x,-y)[/tex]
Apply that to the point: [tex](4,-6.5)\rightarrow(4,6.5)[/tex].
Reflection across the y axis: [tex](x,y)\rightarrow(-x,y)[/tex]
Apply that to the point: [tex](4,-6.5)\rightarrow(-4,-6.5)[/tex]
Hope this helps.
