Question

In the cordinate plane what is the length of the line segment that connects points at (0, -1) and (-7, -2) ? Enter your answer in the box. Round to the nearest hundredth.

Answer 1

≈ 7.07

Explanation:

Calculate the length using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (0, - 1) and (x₂, y₂ ) = (- 7, - 2)

d =
`√((-7-0)^2+(-2+1)^2)`

=
`√((-7)^2+(-1)^2)`

=
`√(49+1)` =
`√(50)` ≈ 7.07
