Answer :
The given points are (-2,4) and (2,4).
To find the distance between these points, we use the distance formula.
[tex]d=\sqrt[]{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]Where,
[tex]\begin{gathered} x_1=-2 \\ x_2=2 \\ y_1=4 \\ y_2=4 \end{gathered}[/tex]Replacing these coordinates, we have
[tex]\begin{gathered} d=\sqrt[]{(2-(-2))^2+(4-4)^2} \\ d=\sqrt[]{(2+2)^2+(0)^2}=\sqrt[]{(4)^2+0}=\sqrt[]{16} \\ d=4 \end{gathered}[/tex]
