Question

Find the distance between (8,2) and (-1,0).

Answer 1

The given points are (8,2) and (-1,0).

We just need to use the following formula and the given points

`d=√((x_2-x_1)^2+(y_2-y_1)^2)`

Replacing the given points, we have

`\begin{gathered} d=√((-1-8)^2+(0-2)^2) \\ d=√((-9)^2+(-2)^2) \\ d=√(81+4)=√(85)\approx9.2 \end{gathered}`

Therefore, the distance between the given points is 9.2 units, approximately.
