Question

What is the distance between the points (−7, 1) and (−7, −5) on the coordinate plane, in units?

Answer 1

6 units

Explanation:

Calculate the distance d using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 7, 1) and (x₂, y₂ ) = (- 7, - 5)

d =
`√((-7+7)^2+(-5-1)^2)`

=
`√(0+(-6)^2)` =
`√(36)` = 6 units
