The distance between two points is given as;
[tex]D=\sqrt[]{(y_2-y_{1_{}})^2+(x_2-x_1)^2}[/tex][tex]\begin{gathered} \text{Where x}_1=-2 \\ y_1=-3 \\ x_2=1 \\ y_2=4 \end{gathered}[/tex][tex]\begin{gathered} D=\sqrt[]{(4-(-3)^2+(1-(-2)^2} \\ D=\sqrt[]{7^2+3^2} \\ D=\sqrt[]{49+9} \\ D=\sqrt[]{58} \end{gathered}[/tex]The number beneath the radical symbol is 58.
