Question

Use A(-1, -2) and B(8,0) to find the length of AB. Round your answer to the nearest hundredth.

Answer 1

9514 1404 393

Answer:

  9.22

Step-by-step explanation:

The distance formula is ...

  d = √((x2 -x1)^2 +(y2 -y1)^2)

Using the given coordinates, the distance between them is ...

  d = √((8-(-1))^2 +(0 -(-2))^2) = √(9^2 +2^2) = √85 ≈ 9.22

The length of AB is about 9.22 units.
