Mathematics for IGCSE & O level - Vectors (Section 2 - No. 20)
Given the points A(1, -1) and B(3, 2), the vector \(\vec{AB}\) is:
\(\begin{pmatrix} 4 \\ 1 \end{pmatrix}\)
\(\begin{pmatrix} 2 \\ 3 \end{pmatrix}\)
\(\begin{pmatrix} -2 \\ -3 \end{pmatrix}\)
\(\begin{pmatrix} -2 \\ 3 \end{pmatrix}\)
Explanation
AB = B - A = (3, 2) - (1, -1) = (2, 3) which is \(\begin{pmatrix} 2 \\ 3 \end{pmatrix}\)
