D x2. If O is the origin and P x y is any point then from distance formula OP 2. Using the distance formula shown in the above article find the horizontal distance between the two points by subtracting -8 from 2 which is 10.
C c is the longest.
The Distance Formula itself is actually derived from the Pythagorean Theorem which is. It is an expansion of the Pythagorean theorem that allows us to use x and y coordinates instead of right triangle side lengths. Using the distance formula shown in the above article find the horizontal distance between the two points by subtracting -8 from 2 which is 10. The given distance between two points calculator is used to find the exact.
