In order to find the coordinates of the vector AB, if the coordinates of its beginning and end are given, it is necessary to subtract the corresponding coordinates of its beginning from the coordinates of the end: AB = (xB – xA; yB – yA). Substituting the corresponding values in the formula, we get: AB = (1 – 3; – 6 + 4) = (- 2; – 2).
Answer: AB (- 2; – 2).
