The transformation over the x-axis has the following rule:
[tex](x,y)\to(x,-y)[/tex]
The coordinates of the point W are:
[tex](x,y)=(-8,-7)[/tex]
Applying the rule above, we have the new coordinates to be:
[tex]\begin{gathered} W^{\prime}\Rightarrow(-8,-(-7) \\ W^{\prime}\Rightarrow(-8,7) \end{gathered}[/tex]
The new coordinates after the transformation are (-8, 7).
