Question

Using Desmos.com or the Pythagorean Theorem find the distance between points A and B rounded to the nearest tenth.

A(-3,4) B(2,-3)

Answer 1

AB ≈ 8.60

Explanation:

Calculate AB using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = A(- 3, 4) and (x₂, y₂ ) = B(2, - 3)

AB =
`√((2+3)^2+(-3-4)^2)`

=
`√(5^2+(-7)^2)`

=
`√(25+49)`

=
`√(74)` ≈ 8.60 ( to the nearest tenth )
