Question

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

Answer 1

Answer:

(B) 3.6

Step-by-step explanation:

Coordinate of A = (-3, 9)

Coordinate of B = (-1, 6)

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

$\text {Distance = }\sqrt{(- 2 )^2 + (3)^2}$

$\text {Distance = }\sqrt{13}$

$\text {Distance = }3.6$

Answer 2

Answer:

B

Step-by-step 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 = $\sqrt{-1+3)^2+(6-9)^2}$

  = $\sqrt{2^2+(-3)^2}$

  = $\sqrt{4+9}$

= $\sqrt{13}$ ≈ 3.6 → B
