IGCSE Math B 8.B Vector notation Topic Practice

The coordinates of point A are (1,8) and the coordinates of point B are (10,-4).

Write down $\overrightarrow{AB}$ as a column vector.

The points A and B are such that the coordinates of A are (3,-2) and
$$\overrightarrow{BA}=\binom{-1}{4}.$$

Find the coordinates of point B.

Diagram NOT accurately drawn.

Figure 2 shows a quadrilateral ABCD with
$$\overrightarrow{AB}=\binom{8.5}{4.5}\quad\text{and}\quad \overrightarrow{AC}=\binom{15}{5}.$$
The diagonals AC and BD meet at the point E.

Find, as a column vector, $\overrightarrow{BC}$.
