Question

Find the distance between the two points if rounded to the nearest tenth (-6,6) and (-3,3)

Answer 1

3
`√(2)` units

Explanation:

Given parameters:

Coordinates = (-6,6) and (-3,3)

Unknown:

The distance between them = ?

Solution:

To find the distance between two points, we use the expression below;

D =
`\sqrt{(x_(2) - x_(1))^(2) + (y_(2) - y_(1))^(2) }`

x₁ = -6 x₂ = -3

y₁ = 6 y₂ = 3

D =
`\sqrt{(-3 -(-6))^(2) + (3-6)^(2) }` =
`√(18)`

D = 3
`√(2)` units
