## Precalculus: Concepts Through Functions, A Unit Circle Approach to Trigonometry (3rd Edition)

$\sqrt{85}$ units
To calculate the distance $d$ between two points, we have: $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ Substitute the $x$ and $y$-coordinates of the given points to obtain: $d=\sqrt{[6-(-3)]^2+(0-2)^2}=\sqrt {81+4}=\sqrt{85}$
