Question

Q(-2, 3) and P (2, 1)
Find the length of the segment. Simplify each radical,if possible

Answer 1

9514 1404 393

Answer:

  2√5

Step-by-step explanation:

The distance formula is useful for this.

  d = √((x2 -x1)² +(y2 -y1)²)

  d = √((2 -(-2))² +(1 -3)²) = √(4² +(-2)²) = √20

  d = 2√5

The length of segment PQ is 2√5.
