Given Coordinates: x1 = 1 y1 = 2, x2 = -1 y2 = 4
Distance Formula: d = √(x2 − x1)2 + (y2 − y1)2
Substitute the given coordinates into the Distance Formula and Simplify:
d = √(-1 − 1)2 + (4 − 2)2
d = √(-2)2 + 22
d = √4 + 4
d = √8
d = √4 * 2
d = √4 * √2
d = 2√2
Therefore, the distance between the points (1, 2) and (-1, 4) is equal to 2√2
Note: As a decimal number, 2√2 ≈ 2.8284271247462
