Dla danych punktów A(x₁, y₁) i B(x₂, y₂):

$\overrightarrow{AB}=\left[x_2-x_1,y_2-y_1\right]$  

---

$\text{a)}\overrightarrow{AB}=\left[4-\left(-2\right),0-3\right]=\left[6,-3\right]$  

$\text{b)}\overrightarrow{AB}=\left[2-0,2\sqrt{3}-\left(-\sqrt{3}\right)\right]=\left[2,3\sqrt{3}\right]$  

$\text{c)}\overrightarrow{AB}=\left[1-\frac{1}{2},3-\frac{1}{3}\right]=\left[\frac{1}{2},2\frac{2}{3}\right]$  

$\text{d)}\overrightarrow{AB}=\left[5\frac{1}{2}-\left(-4\right),-6-8\right]=\left[9\frac{1}{2},-14\right]$
