Answer:
5
Step-by-step explanation:
We need to utilize the pythagorean theorem:
The change in y :
|-2 - 2| = |-4| = 4
The change in x:
|-2 - 1| = |-3| = 3
4 and 3 are the legs, and the distance from the two points is the hypotenuse
Pythagorean Theorem: a² + b² = c²
4² + 3² = c²
16 + 9 = c²
25 = c²
c = √25
c = 5
