Question

What is the distance between A and B? Round your answer to the nearest tenth. (4 points)

A coordinate plane is shown. Point A is located at negative 1, 5, and point B is located at 4, 1. A line segment connects the two points.

6.4

7.3

8.2

9.1

Answer 1

The distance formula is given by:

d = √((x2 - x1)^2 + (y2 - y1)^2)

Plugging in the coordinates of A (-1, 5) and B (4, 1):

d = √((4 - (-1))^2 + (1 - 5)^2)

d = √((5)^2 + (-4)^2)

d = √(25 + 16)

d = √41

Since the problem asks to round the answer to the nearest tenth, the distance between A and B is approximately 6.4.

Therefore, the answer is 6.4.
