How to find the difference between two points

[From: ] [author: ] [Date: 11-09-18] [Hit: ]

:)-Use the formula (y1-y2)/divided by (x1-x2) so this means you would do (12--1) / (3--5) which would equal 13/ divided by 8 or 13/8.Get the vector AB,Magnitude = |AB| = sqrt((-8)^2 + (-13)^2) = sqrt(233)-Use the distance formula.http://www.purplemath.com/modules/distform.......

For example:

A(3, 12), B(-5, -1)

Also, please explain how you got the answer for the example! Thanks! :)

Use the formula (y1-y2)/divided by (x1-x2) so this means you would do (12--1) / (3--5) which would equal 13/ divided by 8 or 13/8.

vector

Get the vector AB, which would be <-8, -13>

use the distance formula sqrt(x^2 + y^2)

Magnitude = |AB| = sqrt((-8)^2 + (-13)^2) = sqrt(233)

Use the distance formula. It's listed here:
