Given Coordinates: x1 = -1 y1 = 2, x2 = 0 y2 = 1
Distance Formula: d = √(x2 − x1)2 + (y2 − y1)2
Substitute the given coordinates into the Distance Formula and Simplify:
d = √(0 − (-1))2 + (1 − 2)2
d = √(0 + 1)2 + (1 − 2)2
d = √12 + (-1)2
d = √1 + 1
d = √2
Therefore, the distance between the points (-1, 2) and (0, 1) is equal to √2
Note: As a decimal number, √2 ≈ 1.4142135623731
