Question

Distance formula A (-1,5) B (0,8)

Answer 1

A = (-1, 5) = (x1, y1)

B = (0,8) = (x2, y2)

Using the distance formula:

`\begin{gathered} d^2={\left({x}_2-{x}_1\right)}^2+{\left({y}_2-{y}_1\right)}^2\Rightarrow d=\sqrt{{\left({x}_(2)-{x}_(1)\right)}^(2)+{\left({y}_(2)-{y}_(1)\right)}^(2)} \\ d=√((0--1)^2+(8-5)^2) \\ d=√(1^2+3^2)=√(1+9)=√(10) \\ d=3.162 \end{gathered}`
