Answer

$\mathbf{v}=-8\mathbf{i}+11\mathbf{j}$

Work Step by Step

Here, $\begin{align} & {{x}_{1}}=2 \\ & {{x}_{2}}=-6 \\ & {{y}_{1}}=-5 \\ & {{y}_{2}}=6 \\ \end{align}$ Substituting the value of ${{x}_{1}},{{y}_{1}},{{x}_{2}},{{y}_{2}}$ we get, $\begin{align} & \mathbf{v}=\left[ -6-2 \right]\mathbf{i}+\left[ 6-\left( -5 \right) \right]\mathbf{j} \\ & =-8\mathbf{i}+11\mathbf{j} \end{align}$
