# How do you find the magnitude of YZ given Y(-2,5) and Z(1,3)?

$| Y Z | = \sqrt{13}$
Magnitude of $Y Z$ given $Y \left(- 2 , 5\right)$ and $Z \left(1 , 3\right)$
is given by $| Y Z | = \sqrt{{\left(1 - \left(- 2\right)\right)}^{2} + {\left(3 - 5\right)}^{2}}$
= $\sqrt{{3}^{2} + {2}^{2}} = \sqrt{9 + 4} = \sqrt{13}$
