i have to find the distance form the swings to fountain. help please

The first thing we have to do is locate the points where the swings and the fountain are located on the graph.
[tex]\begin{gathered} Fountain\to(-2,-2) \\ Swings\to(5,-2) \end{gathered}[/tex]To calculate the distance between the 2 points we use the following equation:
[tex]\begin{gathered} D(F,S)=\sqrt[]{(x_2-x_1)^2-(y_1-y_1)^2} \\ \end{gathered}[/tex]We replace the values of the points F and S:
[tex]\begin{gathered} D(F,S)=\sqrt[]{(5_{}-(-2)_{})^2-(-2_{}-(-2)_{})^2} \\ D(F,S)=\sqrt[]{(5_{}+2_{})^2-(-2_{}+2_{})^2} \\ D(F,S)=\sqrt[]{(7_{})^2-(0_{})^2} \\ D(F,S)=\sqrt[]{(7)^2} \\ D(F,S)=7 \end{gathered}[/tex]
