Question

Find the distance between the given points (2,8) and (7,7)

Answer 1

`d=√(26)\approx5.0990`

Explanation:

To find the distance between any two points, we can use the distance formula.

The distance formula is:

`d=√((x_2-x_1)^2+(y_2-y_1)^2)`

Let (2,8) be x₁ and y₁ and let (7,7) be x₂ and y₂. Thus:

`d=√((7-2)^2+(7-8)^2)`

Simplify:

`d=√(5^2+(-1)^2)`

Square:

`d=√(25+1)`

Add:

`d=√(26)\approx5.0990`

And that's our answer :)
