Question

Find the distance between Point A (-3, – 4) and Point B (1, 5), correct to 2 decimal places.

Answer 1

`\begin{gathered} \text{Let:} \\ (x1,y1)=(-3,-4) \\ (x2,y2)=(1,5) \\ d=\sqrt[]{(x2-x1)^2+(y2-y1)^2} \\ d=\sqrt[]{(1-(-3))^2+(5-(-4))^2}^{}=\sqrt[]{16+81}=\sqrt[]{97}\approx9.85 \end{gathered}`
