Question

How long is the segment from(-5,2)to(-5,-8)

Answer 1

10

Explanation:

To calculate the distance d use the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 5, 2) and (x₂, y₂ ) = (- 5, - 8)

d =
`√((-5+5)^2+(-8-2)^2)`

=
`√(0^2+(-10)^2)`

=
`√(0+100)` =
`√(100)` = 10
