Answer:
13.9 (Answer C)
Step-by-step explanation:
As we go from (-3, 9) to (9, 2), x increases by 12 and y decreases by 7.
Picture a triangle with base 12 and height 7, Use the Pythagrean Theorem to find the length of the hypotenuse, which represents the distance between (-3, 9) and (9, 2):
distance = √(12² + 7²) = √(144 + 49) = √193.
To the nearest tenth, this distance is 13.9 (Answer C)
