Question

What is the distance in units between (-1, -5) and (-9,-5) on a coordinate plane​

Answer 1

8 units

Explanation:

Calculate the distance (d) using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 1, - 5) and (x₂, y₂ ) = (- 9, - 5)

d =
`√((-9+1)^2+(-5+5)^2)`

=
`√((-8)^2+0^2)`

=
`√(64)`

= 8 units
