Question

What is the distance between point A and point B? Round your answer to the nearest tenth.

A. 5

B 3.6

C. 6

D. 2.2

Answer 1

B

Explanation:

Calculate the distance using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = A(- 3,9) and (x₂, y₂ ) = B(- 1, 6)

d =
`√(-1+3)^2+(6-9)^2)`

=
`√(2^2+(-3)^2)`

=
`√(4+9)`

=
`√(13)` ≈ 3.6 → B

Answer 2

(B) 3.6

Explanation:

Coordinate of A = (-3, 9)

Coordinate of B = (-1, 6)

`\text {Distance = }√((- 3 - (-1) )^2 + (9 - 6)^2)`

`\text {Distance = }√((- 2 )^2 + (3)^2)`

`\text {Distance = }√(13)`

`\text {Distance = }3.6`
