Transcript text: Find the vector $\overrightarrow{A B}$ in $\mathbb{R}^{2}$ given in the figure.
\[
\overrightarrow{A B}=\square(1) \text { help (vectors) }
\]
Solution
Find the vector \(\overrightarrow{AB}\) in \(\mathbb{R}^2\) given in the figure.
Identify the coordinates of points A and B.
From the graph, point A has coordinates \((3, -1)\), and point B has coordinates \((-1, 0)\).
Write the vector \(\overrightarrow{AB}\).
The vector \(\overrightarrow{AB}\) is given by \(B - A\). In coordinate form, this is \((-1 - 3, 0 - (-1)) = (-4, 1)\).
