Find the distance between points A (-1; 3) and B (2; -1)
| August 16, 2021 | education
The distance between two points is calculated using the formula:
d = √ (x2 – x1) ^ 2 + (y2 – y1) ^ 2, where (x1; y1) and (x2; y2) are the coordinates of these points.
Two points A (-1; 3) and B (2; -1) are given with coordinates:
x1 = -1; y1 = 3; x2 = 2; y2 = -1.
Let’s calculate the distance between these points:
d = √ (2 – (-1)) ^ 2 + (-1 – 3) ^ 2 = √9 + 16 = √25 = 5.
Answer: the distance between points A (-1; 3) and B (2; -1) is 5.
