#### Explanation:

The distance between two points A(x;y) and B(x';y') can be calculate with the formula :

Then for : A(-3;-2) and B(1;4) we have :

The distance between A(-3;-2) and B(1;4) is exactly

Why this formula work ? In fact, we only calculate the length of vector(BA), and we implicitly use the Pythagorean theorem on it.
