Question

Дано точки А（-2:3）Б（1:-1）С（2:4）Знайдіть координати векторів АВ і СА

Answer 1

Координаты вектора равны разности соответствующих координат точек его конца и начала.
Вектор АВ{Xb-Xa;Yb-Ya} или AB{1-(-2);-1-3} или AB{3;-4}.
Вектор СА(-2-2;3-4) или СА{-4;-1}.

Answer 2

Finding the Coordinates of Vectors AB and CA

To find the coordinates of vectors AB and CA, we need to subtract the coordinates of point A from the coordinates of point B and point C, respectively.

The coordinates of point A are (-2, 3). The coordinates of point B are (1, -1). The coordinates of point C are (2, 4).

To find the coordinates of vector AB, we subtract the coordinates of point A from the coordinates of point B: AB = (1, -1) - (-2, 3) = (1 - (-2), -1 - 3) = (3, -4)

To find the coordinates of vector CA, we subtract the coordinates of point C from the coordinates of point A: CA = (-2, 3) - (2, 4) = (-2 - 2, 3 - 4) = (-4, -1)

Therefore, the coordinates of vector AB are (3, -4), and the coordinates of vector CA are (-4, -1).
