#### Answer

$(2,4)$

#### Work Step by Step

$A(-5,-1),B(-3,3)$
$a$ is the vector from A to B, find it by subtracting the corresponding components of A from B.
$a=AB=\lt-3-(-5),3-(-1) \gt =\lt 2,4\gt $
The equivalent representation starting at the origin is a vector from point $(0,0)$ to the point $(2,4)$.
