Given Coordinates: x1 = 1 y1 = 2, x2 = -1 y2 = -2
Distance Formula: d = √(x2 − x1)2 + (y2 − y1)2
Substitute the given coordinates into the Distance Formula and Simplify:
d = √(-1 − 1)2 + (-2 − 2)2
d = √(-2)2 + (-4)2
d = √4 + 16
d = √20
d = √4 * 5
d = √4 * √5
d = 2√5
Therefore, the distance between the points (1, 2) and (-1, -2) is equal to 2√5
Note: As a decimal number, 2√5 ≈ 4.4721359549996
