Answer:

see explanation

Explanation:

given the endpoint (x, y)

the component form is
$\left[\begin{array}{ccc}x\\y\\\end{array}\right]$

the component form of (3, - 2 ) is
$\left[\begin{array}{ccc}3\\-2\\\end{array}\right]$

the magnitude of a vector
$\left[\begin{array}{ccc}x\\y\\\end{array}\right]$ is

√(x^2+y^2)

hence magnitude =
√(3^2+(-2)^2) =
√(9+4) =
√(13)
