Question

The distance between the points (2,8) and (4,7) is

Answer 1

it is 5!!

Explanation:

Answer 2

`√(5)`

Explanation:

Calculate the distance d using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (2, 8) and (x₂, y₂ ) = (4, 7)

d =
`√((4-2)^2+(7-8)^2)`

=
`√(2^2+(-1)^2)`

=
`√(4+1)`

=
`√(5)` ≈ 2.24 ( to 2 dec. places )
