Distance Formula
How to find the distance between two points by using the distance formula: formula, 1 example, and its solution.
Formula
Formula
The distance between two points (x1, y1) and (x2, y2) is
d = √(x2 - x1)2 + (y2 - y1)2.
This is the distance formula.
Example
Example
Solution
The given points are (-3, 1) and (5, 4).
Then the distance d is,
x2 - x1, 5 - (-3)
square
plus,
y2 - y1, 4 - 1
square.
5 - (-3) = 5 + 3
4 - 1 = 3
5 + 3 = 8
82 = 64
+32 = +9
64 + 9 = 73
So d = √73 is the answer.
