Question

Find the distance between (-2, -2) and (1, 2).

Answer 1

5

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
