Explanation:

The given points are:

[tex]y(-2,5) \\ \\ z(1,3)[/tex]

So, the vector [tex]\vec{yz}[/tex] is:

[tex]\vec{yz}=\vec{z}-\vec{y} \\ \\ \vec{yz}=(1,3)-(-2,5) \\ \\ \vec{yz}=(1+2,3-5) \\ \\ \vec{yz}=(3,-2)[/tex]

And the magnitude:

[tex]\mid \vec{yz} \mid=\sqrt{(3)^2+(-2)^2} \\ \\ \mid \vec{yz} \mid=\sqrt{9+4} \\ \\ \mid \vec{yz} \mid=\sqrt{13}[/tex]
