My teacher gave us this problem to practice on but I forgot how he solved it. Can you please show me

We can calculate the distance between two points using the following formula
[tex]D=\sqrt[]{(x_1-x_2)^2+(y_1-y_2)^2}[/tex]where,
(x1,y1) = (3,6)
(x2,y2) = (-1,1)
Replace
[tex]D=\sqrt[]{(3-(-1)^2+(6-1)^2}[/tex]Solve
[tex]\begin{gathered} D=\sqrt[]{(4)^2+(5)^2} \\ =\sqrt[]{16+25} \\ =\sqrt[]{41} \\ =6.4031 \end{gathered}[/tex]rounding to the nearest tenth of a klick
D = 6.4 Klicks
