Question

The coordinates of point A(-3,2) and the coordinates of point B(4,1) what is the length of AB?

Answer 1

9514 1404 393

Answer:

AB = 5√2

Explanation:

The length of AB is given by the distance formula:

d = √((x2 -x1)² +(y2 -y1)²)

d = √((4 -(-3))² +(1 -2)²) = √(7² +(-1)²) = √(49 +1) = √50

The length of AB is √50 = 5√2.
