Question

What is the exact distance from (-1,4) to (6,-2)? in units​

Answer 1

`√(85)`

Explanation:

To calculate the distance (d) use the distance formula

d = √ (x₂ - x₁ )² + ( y₂ - y₁ )²

with (x₁, y₁ ) = (- 1, 4) and (x₂, y₂ ) = (6, - 2)

d =
`√((6+1)^2+(-2-4)^2)`

=
`√(7^2+(-6)^2)`

=
`√(49+36)` =
`√(85)` ← exact distance
