Question

Find the distance between the two points rounding to the nearest tenth (if necessary). (-2,-9) and (3,3)

Answer 1

$\begin{gathered} \text{Here, } \\ x_1=-2,x_2=3, \\ y_1=-9,y_2=3 \\ \text{The distance between the points is } \\ d=\sqrt[]{(x_2-x_1)^2+(y_2-y_1)^2} \\ d=\sqrt[]{(3+2)^2+(3+9)^2} \\ d=\sqrt[]{5^2+12^2} \\ d=\sqrt[]{25+144} \\ d=\sqrt[]{169} \\ d=13 \end{gathered}$
