What is the length of MN?
Round to the nearest tenth of a unit.
??? Units

Answer:
8.5
Step-by-step explanation:
The length of a segment can be found from its end coordinates by using the distance formula:
d = √((x2 -x1)² +(y2 -y1)²)
d = √((8 -2)² +(4 -(-2))²) = √(6² +6²) = √72
d ≈ 8.485 ≈ 8.5
The length of MN is about 8.5 units.
